By Allah if you do not let him go...
By Allah if you do not let him go, I will uncover my head, rip my shirt, and go to my Father's tomb and cry to my Lord..." So, she (Fatima az-Zahra (sa)) took Al-Hasan (as) and Al-Husayn's (as) hands, and proceeded towards her father's (as) tomb!
When Imam ‘Ali (as) saw the seriousness of the situation, he immediately interfered, and said to Salman: "Prevent Muhammad's daughter (from reaching her father's grave) for surely I can see the outskirts of Medina being sunk into the earth." Salman later said: "I was near Lady Fatima (sa) when, by Allah, I saw the foundations of the Mosque's walls being elevated up to a point that had a man wanted to go from under them, he would have been able to do so.
So I said: `My Mistress, surely Allah, the Exalted, sent your father to be mercy, thus do not become the cause of His wrath. "' These noble stands of Fatima az-Zahra (sa), forced Abu Bakr and Umar to release ‘Ali (as) ; Fatima az-Zahra (sa) returned home after setting the most honorable example of devotion to her husband.
Encounters in the Mosque: As we have already mentioned, Abu Bakr sent Umar to Fatima’s (sa) house with orders to compel ‘Ali (as) and his friends to come and pledge allegiance to him. If they could not be persuaded by fair means, Umar was going to set the house on fire. When Fatima az-Zahra (sa) asked him what he meant, he told her that he would certainly burn the house down unless they would be content to do as the rest of the people had done.

You claim the succession to the Prophet of Allah preferring your priority in Islam and your kinship, to him before the Ansars. Now, I put forward the same arguments in preference to you. Am I not the first who believed in the Prophet before any of you embraced his faith?
Am I not the nearest in relation to the Prophet than any of you? Fear Allah, if you are true believers, and do not snatch away the Prophet's authority from his house to your own." Standing behind the door, Fatima az-Zahra (sa) reproachfully addressed the raiding people thus: "O people! You left behind the Prophet's dead body to us, and proceeded to wring out the Caliphate for yourselves, extinguishing our rights." She (sa) then burst into tears and cried: "O Father! O Prophet of Allah!
