It was narrated that Zuhri heard Anas bin Malik say:
“The last glance that I had of the Messenger of Allah ﷺ was when he drew back the curtain on Monday, and I saw his face as if it was a page of the Mushaf (Qur’an), and the people were praying behind Abu Bakr. He (Abu Bakr) wanted to move, but he (the Prophet ﷺ) gestured to him to stand firm. Then he let the curtain fall, and he died at the end of that day.”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ آخِرُ نَظْرَةٍ نَظَرْتُهَا إِلَى رَسُولِ اللَّهِ ﷺ كَشْفُ السِّتَارَةِ يَوْمَ الاِثْنَيْنِ فَنَظَرْتُ إِلَى وَجْهِهِ كَأَنَّهُ وَرَقَةُ مُصْحَفٍ وَالنَّاسُ خَلْفَ أَبِي بَكْرٍ فِي الصَّلاَةِ فَأَرَادَ أَنْ يَتَحَرَّكَ فَأَشَارَ إِلَيْهِ أَنِ اثْبُتْ وَأَلْقَى السِّجْفَ وَمَاتَ مِنْ آخِرِ ذَلِكَ الْيَوْمِ .
