The Apostle of Allah ﷺ did not come to us for three days. When the prayer was about to start. Abu Bakr stepped forward (to lead the prayer), and the Messenger of Allah ﷺ lifted the curtain. When the face of the Messenger of Allah ﷺ became visible to us, we (found) that no sight was more endearing to us than the face of the Messenger of Allah ﷺ as it appeared to us. The Apostle of Allah ﷺ with the gesture of his hand directed Abu Bakr to step forward (and lead the prayer). The Apostle of Allah ﷺ then drew the curtain, and we could not see him till he died. (Using translation from Muslim 419d)
لَمْ يَخْرُجْ إِلَيْنَا نَبِيُّ اللهِ ﷺ ثَلَاثًا وَأُقِيمَتِ الصَّلَاةُ فَذَهَبَ أَبُو بَكْرٍ يَتَقَدَّمُ فَقَالَ النَّبِيُّ ﷺ بِالْحِجَابِ فَرَفَعَهُ فَلَمَّا وَضَحَ لَنَا وَجْهُ نَّبِيِّ اللهِ ﷺ مَا نَظَرْنَا مَنْظَرًا قَطُّ كَانَ أَعْجَبَ إِلَيْنَا مِنْ وَجْهِ نَبِيِّ اللهِ ﷺ حِينَ وَضَحَ لَنَا فَأَوْمَأَ بِيَدِهِ ﷺ إِلَى أَبِي بَكْرٍ أَنْ يَتَقَدَّمَ وَأَرْخَى نَبِيُّ اللهِ ﷺ الْحِجَابَ فَلَمْ يَقْدِرَ عَلَيْهِ حَتَّى مَاتَ
