Ash-Shama'il Al-Muhammadiyah, Book 53, Hadith 368 (English) ⓘ

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".

حَدَّثَنَا أَبُو عَمَّارٍ الْحُسَيْنُ بْنُ حُرَيْثٍ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، وَغَيْرُ وَاحِدٍ، قَالُوا‏:‏ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ‏:‏ آخِرُ نَظْرَةٍ نَظَرْتُهَا إِلَى رَسُولِ اللهِ صلى الله عليه وسلم، كَشْفُ السِّتَارَةِ يَوْمَ الاثْنَيْنِ، فَنَظَرْتُ إِلَى وَجْهِهِ كَأَنَّهُ وَرَقَةُ مُصْحَفٍ، وَالنَّاسُ خَلْفَ أَبِي بَكْرٍ، فَكَادَ النَّاسُ أَنْ يَضْطَربُوا، فَأَشَارَ إِلَى النَّاسِ أَنِ اثْبُتُوا، وَأَبُو بَكْرٍ يَؤُمُّهُمْ وَأَلْقَى السِّجْفَ، وَتُوُفِّيَ رَسُولُ اللهِ صلى الله عليه وسلم مِنْ آخِرِ ذَلِكَ الْيَوْمِ‏.‏
