Few words of Amir-ul-Momenin when Hazrat Fatima martyred. Few words which can lead any person to real. And many questions can raise.

What prophet has been told in last minutes of his life and how his daughter has been martyred?

Martyrdom of Hazrat Fatima (A.S.)
What Amir-ul-Mo’mineen said on the occasion of the burial of Sayyidatu’n-nisa’ (the Supreme Lady) Fatima (A.S.) while addressing the Holy Prophet at his grave.
O’ Prophet of Allah, peace be upon you from me and from your daughter, who has come to you and who has hastened to meet you. O’ Prophet of Allah, my patience (regarding the separation) from your chosen (daughter) has decreased, and my endurance has diminished; except what calms me is that I endured the sorrowful and heart-rending event of your separation. I was the one who laid you down in your grave when your last breath had passed away, (while your head was) between my neck and chest.
” … Verily we are Allah’s and verily unto Him shall we return. (Quran, 2:156)
O’ Prophet, What you entrusted to me has been returned and what I had been given has been taken back. As to my grief, it is never-ending, and as to my nights, they will remain sleepless till Allah chooses for me the house in which you are now residing (till my death).
Certainly, your daughter will inform you regarding the unification of your people to oppress her. Ask her the details and the specifics of the situation. This has occurred not long after your time, and you have still not been forgotten. My Salaam (Salutation) be on you both, the Salaam of farewell, not of annoyance or tiredness; for if I go away it is not because I am weary (of you), and if I stay is not due to a lack of belief in what Allah has promised the enduring.
