"In the last prayer that the Messenger of Allah ﷺ prayed with the people, he prayed wrapped up in a single garment, behind Abu Bakr."  

آخِرُ صَلاَةٍ صَلاَّهَا رَسُولُ اللَّهِ ﷺ مَعَ الْقَوْمِ صَلَّى فِي ثَوْبٍ وَاحِدٍ مُتَوَشِّحًا خَلْفَ أَبِي بَكْرٍ  

It was narrated from Aisha that Abu Bakr led the people in prayer and the Messenger of Allah ﷺwas in the row.  

أَنَّ أَبَا بَكْرٍ صَلَّى لِلنَّاسِ وَرَسُولُ اللَّهِ ﷺ فِي الصَّفِّ
