Anas (may Allah be pleased with him) narrates:
"The last glimpse I had of Messenger of Allah ﷺ 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 (may Allah be pleased with him). 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 Messenger of Allah ﷺ became ill, Abubakr (may Allah be pleased with him) led the salaah. When he was recovering he would come and join the congregational prayer). Messenger of Allah ﷺ made a sign to the people to remain in their places. Messenger of Allah ﷺ 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 ﷺ، 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 ﷺ مِنْ آخِرِ ذَلِكَ الْيَوْمِ.
