Hadith 2:154
Sahih (Al-Albani)
Anas reported :
the Iqamah was pronounced (for the night prayer) and the Messenger of Allah (ﷺ) remained engaged in talking (to a person) in the corner of the mosque. He did not begin prayer until the people slept.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسٍ، قَالَ أُقِيمَتِ الصَّلاَةُ وَرَسُولُ اللَّهِ صلى الله عليه وسلم نَجِيٌّ فِي جَانِبِ الْمَسْجِدِ فَمَا قَامَ إِلَى الصَّلاَةِ حَتَّى نَامَ الْقَوْمُ
