So this is far behind the developments of Saqifah and other events pertaining to Caliphate. As such, the claim is absolutely wrong. Secondly: With regard to marriage of Ali and Zahra, Sunni scholars have written from reliable sources that the Prophet said: Indeed, the Almighty Allah has commanded me to give my daughter, Fatima in marriage to Ali (a.s.).
It is when the two of them (Abu Bakr and Umar) had separately gone to him for the hand of Fatima for themselves and got a negative reply…with this detail that in the matter of this marriage that is directly commanded by God Almighty and that also after Abu Bakr and Umar both has been disappointed in their efforts to get the hand of Fatima (s.a.).
You wonder whether these two persons or others had design that it should happen or not?” [2] Some Shia sources narrate the development of seeking Zahra’s hand from the Prophet by those two as follows: “One day Abu Bakr, Umar and Saad bin Maaz were sitting in the mosque of the Prophet. The conversation turned to the marriage of the Prophet’s daughter, Fatima (s.a.). Abu Bakr told Umar and Saad bin Maaz: Get up. Let us go to Ali and ask him to go to the Prophet to seek Zahra’s hand in marriage.
If he is hindered by impecunious circumstances we will support him. So they managed to convince Ali to go…Abu Bakr and Umar sent His Eminence as a test**[3]** and themselves waited for him outside. When Ali came out, they asked: what is the news? His Eminence article quoted in Mashkoot Magazine, Issue No. 2, Spring 62, Pg. 52** [1]** Sayyid Ahmad Mawassaqi: Istiratazi-e-Wahdat (Strategy of Unity), Vol. 1, Pg. 125 [2] Engineer Jawad Husaini Tabatabai: Dar Pasukh-e-Afsana-e-Shahadat, Pgs.
171-173 [3] [Because to anyone who proposed for the hand of Zahra, the Prophet gave a negative reply due to divine orders] said: His Eminence, the Messenger of Allah (s.a.w.s.) has married his daughter Fatima to me and told me that God has performed our marriage in heaven…when Abu Bakr and his companions heard the news they pretended to be happy…” [1] Another case pertaining to the relations of Abu Bakr with Amirul Momineen (a.s.) goes back to the time of Prophet’s flight from Mecca to Yathrib and their halt at Quba; at that time: “Abu Bakr insisted that they enter Medina as soon as possible but the Prophet said: I will not enter Medina unless my brother, I mean, the son of my mother, Ali and my daughter Fatima come and join me.
