Shama-il Tirmidhi Chapter 53, Hadith Number 1 (368).

Anas Radiyallahu ‘Anhu narrates: “The last glimpse I had of Rasulullah Sallallahu ‘Alayhi Wasallam was at the time of his last illness on a Monday morning when he lifted the curtain of his house (to take a look at his ummah performing the salaah). At that time his mubaarak face was shining and clear as if it was a page of the Mus-haf (Qur-aan). At that time the people were performing the (fajr) salaah behind Abubakr Radiyallahu ‘Anhu. The people began moving back (in happiness after seeing him, thinking that he would come to join them. Before this too on an occasion when Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam became ill, Abubakr Radiyallahu ‘Anhu led the salaah. When he was recovering he would come and join the congregational prayer). Rasulullah Sallallahu ‘Alayhi Wasallam made a sign to the people to remain in their places. Rasulullah Sallallahu ‘Alayhi Wasallam passed away on that day”.

This is the last glimpse on the Monday, wherein Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam judged that the shar’ee system has been established, and the old friend Sayyidina Abubakr Radiyallahu ‘Anhu would fulfil his duty, and shoulder the responsibilities of the ummah. Accordingly, this is what took place and what the world witnessed, that the demise of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam was such an occurrence before which all the incidents that took place in the world are of no importance and as if nothing had occurred, and with it the fitnah of apostasy, and the facing of all worldly problems, but this pinnacle of steadfastness endured all its calamities, and with a will stronger than hard rock, overcame all hardships and difficulties. The truth is that Sayyidina Abubakr Radiyallahu ‘Anhu did justice to his responsibilities as a khalifah of Sayyidina Rasulullah Sallallabu ‘Alayhi Wasallam. A pillar of Islaam like Sayyidina ‘Umar Ridiyallahu ‘Anhu, whose courage, strength and ability, friends and enemies alike had accepted, when requesting Sayyidina Abubakr Radiyallahu ‘Anhu to adopt leniency, receives a reply not to be weak-hearted.
