Shama-il Tirmidhi Chapter 53, Hadith Number 2 (369).

‘Aayeshah Radiyallahu ‘Anha relates that at the time of the death of Rasulullah Sallallahu’Alayhi Wasallam, she gave him support with her chest, or she said with her lap. He asked for a container to urinate in. He urinated therein. Thereafter he passed away.

It is a pride for Sayyiditina ‘Aayeshah Radiyallahu ‘Anha that the last moments were spent with her. When Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam passed away from this world and reached his Creator, his head was resting in the lap of Sayyiditina ‘Aayeshah Radiyallahu ‘Anha.
