حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ آخِرُ نَظْرَةٍ نَظَرْتُهَا إِلَى رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ 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 ‏.‏

It wasnarrated that Zuhri heard Anas bin Malik say: “The last glancethatI had of the Messenger of Allah (PBUH) was when he drew back thecurtain on Monday, and I saw his face as if it was a page of theMushaf (Qur’an), and the people were praying behind Abu Bakr. He(AbuBakr) wanted to move, but he (the Prophet (PBUH)) gestured to himtostand firm. Then he let the curtain fall, and he died at the endofthat day.” Translation Not Available
