Aysha Performs latom on the holy Prophet (pbuh)
Ibn Ishaq narrates in his sirah page 713 Beruit print, Dar kutub al-Elimiyah:
Ayesha said "The Messenger of God died on my bosom during my turn, I did not wrong anyone in regard to him. It was because of my ignorance and youthfulness that the Messenger of God died while he was in my lap. Then I laid his head on a pillow and got up beating my chest and slapping my face along with the women"
The Mukhrij of the book for ibn Ishaq declared the above hadith as hassan (relaible).
