Marriage
When Fatima came of age, a number of hopefuls sought her hand in marriage. The Holy Prophet was awaiting the Divine order in this respect until Imam `Ali approached him and asked for her hand in marriage. The Holy Prophet came to Fatima (ع) and asked, "My daughter! Do you consent to be wedded to `Ali, as I am so commanded by Allah?" Fatima (ع) thereupon bowed her head in modesty. Umm Salamah narrates the following: "Fatima’s face Fatima bloomed with joy and her silence was so suggestive and conspicuous that the Holy Prophet stood up to shout: Allahu Akbar' (Allah is great)! Fatima's silence is her acceptance."
On Friday, Thul Hijja 1, 2 A.H., which corresponded to May 25, 624 A.D. according to the Julian Christian calendar or to the 28th of May of the same year according to the Gregorian Christian calendar which is widely used in the text of this book, the marriage ceremony took place. All the Muhajirun (emigrants) and Ansar (supporters) of Medina assembled in the mosque while Imam `Ali was seated before the Holy Prophet with all the ceremonious modesty of a bridegroom.
The Holy Prophet first recited an eloquent sermon then declared: “I have been commanded by Allah to get Fatima wedded to `Ali, and so I do hereby solemnize the matrimony between `Ali and Fatima on a dower of four hundred mithqal of silver.” Then he asked Imam Ali, "Do you consent to it, O Ali? " "Yes, I do, O Holy Prophet of Allah!" replied Imam Ali (ع).
Then the Holy Prophet raised his hands and supplicated thus: “O Lord! Bless both of them, sanctify their progeny and grant them the keys of Your beneficence, Your treasures of wisdom and genius; and let them be a source of blessing and peace to my umma.” Her children; Imam Hasan, Imam Hussain, Zainab and Umm Kulthum, are well-known for their piety, righteousness and generosity. Their strength of character and actions changed the course of history and fortified Islam which otherwise would have been lost to mankind.
As a wife, she was very devoted. She never asked Ali for anything in her entire life. As a mother, she cared for and brought up wonderful children; they have left their marks on the pages of world history which time and the plots of enemies of Ahl al-Bayt (ع) will never be able to erase.
