Narrated AbuBakrah:

The Messenger of Allah (ﷺ) began to lead (the people) in the dawn prayer. He then signalled with his hand: (Stay) at your places. (Then he entered his home). He then returned while drops of water were coming down from him (from his body) and he led them in prayer.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ زِيَادٍ الأَعْلَمِ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَخَلَ فِي صَلاَةِ الْفَجْرِ فَأَوْمَأَ بِيَدِهِ أَنْ مَكَانَكُمْ ثُمَّ جَاءَ وَرَأْسُهُ يَقْطُرُ فَصَلَّى بِهِمْ ‏.‏
