Wilayah of Ahlul Bait

He said: Abul Qasim Ja'far b. Muhammad - may Allah bless him with mercy, reported to me from his father, from Sa'd b. Abdillah, from Ahmad b. Muhammad b. Isa, from Muhammad b. Sinan, from Abdul Karim b. Amru and Ibrahim b. Rahah al-Basri, who both reported from Mayassar, who reported that:
Abu Abdillah Ja'far b. Muhammad, peace be upon him told him: "What do you say about a person who does not disobey in what Allah has enjoined and forbidden, but he disassociates with you and your friends in this matter (i.e. wilayah of Ahlul Bait)?" I said: "What can I say in your presence?" He said: "Say, for I command you to speak." I said: "He will be in hellfire."
Then he said: "O Mayassar, what do you say about a person who has faith similar to yours, and has committed sins normally committed by people, but he refrains from the major sins?" I said: "What can I say in your presence?" He said: "Say, for that is my order." I said: "He will be in Paradise."
He said: "Perhaps you are hesitating in saying that such a person will be in Paradise!" I said: "No"
He said: "Do not hesitate, for surely, Allah, Most High, says (in the Qur'an): 'If you avoid the heinous sins that are forbidden you, We will expiate your evil deeds and admit you in honourable manner.' (al-Nisa:V.31)"
Jabir asked the Prophet about his successor
He said: Abu Nasr Muhammad b. al-Husain al-Muqri reported to me from Abu Abdillah al-Husain b. Ali al-Razi, who reported from Ja'far b. Muhammad al-Hanafi, who reported from Yahya b. Hashim al-Simsar, who reported from Amru b. Shimr, who reported from Hammad, from Abu al-Zubair, from Jabir b. Abdillah b. Harram al-Ansari, who said:
Once I came to the Prophet, peace be upon him and his progeny, and asked: "O messenger of Allah, who is your successor?" He said that the Prophet kept silent for a while, not answering me. Then he said: "O Jabir, may I not answer your question?" So I said: "My father and my mother be your ransom; By Allah, you maintained a silence, till I thought you were not pleased."
He said: "O Jabir, I was not displeased with you. I was waiting for what the heavens would reveal, and then Jibraeel came to me saying: O Muhammad, your Lord sends you salutations and says unto you: Surely, Ali b. Abi Talib is your executor and your successor over your kinsfolk and the Ummah; and a protector of your Pool (al-Hawdh). He is the bearer of your standard, preceding you into Praradise."
I said: "O Prophet of Allah! Would you say that if someone did not believe in this, I should fight him?" He said: "Yes O Jabir. This status has not been established except for being followed. So whoever follows it, he will be with me tomorrow, (i.e. on the day of Judgement) and whoever opposes it, he will never arrive near me at the Pool (al-Hawdh)."
Those who love the Prophet and his progeny
He said: Abu Bakr Muhammad b. Umar al-Je'abi reported to me from Abul Abbas Ahmad b. Muhammad b. Saeed al-Hamdani, who reported from Umar b. Aslam, who reported from Saeed b. Yusuf al-Basri, from Khalid b. Abdul Rahman al-Madayeni, from Abdul Rahman b. Abi Layla, from Abu Dharr al-Ghifari - may Allah be pleased with him, who said:
I saw the Messenger of Allah, peace be upon him and his progeny, stroke the shoulders of Ali b. Abi Talib, peace be upon him and say: "O Ali, whoever loves us is from pure Arab breed and those who hate us are the non-Arab infidels. Our Shias are people of noble descent and honour, and are of legitimate birth. And there is none on the path of Ibrahim except those who are our Shias; the rest of the people are away from it. And Allah has appointed angels who demolish the sins of our Shias, the way a pick destroys a structure."
Weeping for the sufferings of Ahlul Bait
He said: Abu Bakr Muhammad b. Umar al-Je'abi reported to me from Abul Abbas Ahmad b. Muhammad b. Saeed al-Hamdani, who reported from Ahmad b. Abdul Hamid b. Khalid, who reported from Muhammad b. Amru b. Utbah, from al-Husain al-Ashqar, from Muhammad b. Abi Amarah al-Kufi who said:
I heard Ja'far b. Muhammad, peace be upon him, say: "Whoever sheds a tear over our spilled blood, or over our usurped rights, or over the dishonour we have suffered, or any of our followers has suffered, such a person shall be blessed by Allah, Most High, in paradise for a long period of time."
The pillars of faith
He said: Abu Ja'far Muhammad b. Ali b. al-Husain reported to me from his father, who reported from Sa'd b. Abdillah, from Muhammad b. al-Husain b. Abu al-Khattab, from Muhammad b. Sinan, from al-Mufaddhal b. Umar al-Jo'fi, from Jabir b. Yazid, from Abu Ja'far, Muhammad b. Ali al-Husain, from his father, from his forefather, peace be upon them all, who said:
The Prophet, peace be upon him and his progeny, told Ali b. Abi Talib, peace be upon him: "O Ali, I and you, and your two sons Hasan and Husain and nine descendants of Husain are the pillars of faith and buttress of Islam. Those who will follow us will be saved and those who turn away from us, their way is to hellfire."
The love of Ahlul Bait
He said: Abul Qasim Ja'far b. Muhammad b. Qawalawy al-Qummi - may Allah bless him with mercy, reported to me from his father, who reported from Sa'd b. Abdullah, who reported from Ahmad b. Muhammad b. Isa, from al-Hasan b. Ali b. Faddhal, from Asim b. Hamid al-Hannat, from Abu Hamza al-Thumali from Hanash b. al-Mo'tamar, who said:
Once I called upon Amirul Mo'mineen, Ali b. Abi Talib, peace be upon him, while he was at al-Rahbah, reclining. So I said: "Peace be upon you, O, Amirul Mo'mineen and His mercy and His blessing, how are you this morning?" He said: He raised his head and returned the greetings and then said: "I have entered this morning with love for those who love us and patience fro those who hate us. Surely, he who loves us, awaits for repose, happiness and deliverance every day and night. And he who hates us has built a structure whose foundation is laid on the edge of a crumbling bank; which tumbles and tumbles down with him into the fire of hell.
O, Abu Mo'tamar, he who loves us cannot nurse hatred against us in his bosom and he who hates us cannot love us. No doubt, Allah, Most High, created the hearts of the slaves with a propensity to love us and has forsaken those who deviated to hate us. So, those who love us cannot hate us and those who hate us cannot love us; and our love can never be combined with the love of our adversaries in one heart. Allah has not assigned to any man two hearts in his chest - loving one group with this heart and loving those who are their enemies with the other."
Islam begins and ends with the Prophet and Ahlulbait
He said: Abu Bakr Muhammad b. Umar al-Je'abi reported to me from Ali b. Ishaq al-Makhrami, who reported from Uthman b. Abdillah al-Shami, who reported from ibn Luhayah, from Abu Zura'h al-Hadhrami, from Umar b. Ali b. Abi Talib, from his father, peace be upon him that:
The Prophet, peace be upon him and his progeny, said: "O Ali! With us Allah completed His religion, the same way as He initiated it, and with us He will unite your hearts (in love) after the enmity and hatred."
Hatred of Ahlul Bait leads to hell
He said: Abu Bakr Muhammad b. Umar al-Je'abi reported to me from Abdul Karim ibn Muhammad, who reported from Sahl b. Zanjalah al-Razi, who reported from ibn Abi Uways, who reported from his father, who reported from Hamid b. Qais, from Ata from Ibn Abbas, who reported that:
The Prophet, peace be upon him and his progeny, said: "O Children of Abdul Muttalib! I have beseeched Allah to convert the ignorant among you into learned men, and to make you steadfast in your stand, and to guide those of you who are gone astray; and to make you brave, generous and kind. By Allah, if a person were to offer prayers between al-Rukn and al-Maqam (around holy Ka'bah), but at the same time die with hatred towards you, O Ahlul Bait, such a person will enter hellfire."
To obey Ahlul Bait is to obey Allah
He said: Al-Sharif al-Swaleh Abu Muhammad b. Hamza al-Alawi al-Husaini al-Tabari, may Allah bless him with mercy, reported to me from Muhammad b. Abdillah b. Ja'far al-Himyari, from his father, from Ahmad b. Muhammad b. Isa, from Murook b. Ubaid al-Kufi, from Muhammad b. Zaid al-Tabari, who said:
I was present at the residence of al-Ridha, Ali b. Musa, peace be upon him, at Khurasan, and a group of Banu Hashim, including Ishaq b. al-Abbas b. Musa, was present also. So, addressing Ishaq, (al-Ridha) said: "O Ishaq! I have come to learn that you are telling people that we consider them as our slaves. I swear by my relation with the messenger of Allah, peace be upon him and his progeny, I have never said that! Nor did I hear to that effect from my forefathers, nor has it been conveyed to me from them through anyone. Yes, what we have said is that people are subservient to us in matters of obedience to Allah, loyal to us in religion. So let those present here convey this to those who are absent."
The four riders on the day of Qiyamah
He said: Abu Ali al-Hasan b. Ali b. Fadhl al-Razi reported to me from Abul Hasan Ali b. Ahmad b. Bishr al-Askari, who reported from Abu Ishaq Muhammad b. Haroon b. Isa al-Hashimi, who reported from Abu Ishaq Ibrahim b. Mahdi al-Ibili, who reported from Ishaq b. Sulaiman al-Hashimi, who reported from his father, who reported from Haroon al-Rashid, who reported from his father al-Mahdi, who reported from al-Mansur Abu Ja'far Abdullah b. Muhammad b. Ali, from his father, from his grandfather Ali b. Abdillah b. al-Abbas, from Abdillah b. Abbas b. Abdul Muttalib, who said:
I heard the Prophet, peace be upon him and his progeny say: "Four of us will be the riders on the Day of Resurrection and none other." So someone asked: "My father and mother be your ransom, who are the riders?" He said: "I will be riding al-Buraq, and my brother Swaleh will be mounting the god-sent she-camel which was hamstrung by his people, and my daughter Fatimah will be on my bright she-camel, and Ali b. Abi Talib, who will ride one of the she-camels of Paradise, whose bridle will be of fresh pearls, whose eyes will of ruby, whose stomach will of green aquamarine; upon the camel will be cupola of translucent pearls, so that its exterior will be visible from within, and her interior will be seen from outside. Its exterior will be from the mercy of Allah, and its interior will be from His grace. She will be fast as she advances, and also as she retracts. He will be ahead of me.
There will be a crown of light on his head, a crown which will give light to all assembled. It will have seventy corners, each shining like a brilliant star in the heaven; and in his hands will be the praised standard, and he will set forth announcing: 'There is no god but Allah, and Muhammad is His messenger.' And he will pass among the angels, they will say: 'He must be from the sent Prophets.' And as he will pass by the Prophets, they will say: 'He must be an angel nearest to Allah.' And then it will be announced from inside the Throne: 'O people! He is neither an angel nearest to Allah, nor a sent Prophet, nor a carrier of the Throne. He is Ali b. Abi Talib.'
Then his Shiahs will follow, and it will be announced: 'Who are you?' They will say: 'We are the partisans of Ali.' The answer will come: 'O partisans of Ali, you are secure; enter the Paradise and be with those who you loved."
