The Book of Prayer
وَعَنْ أَبِي قَتَادَةٌ فِي اَلْحَدِيثِ اَلطَّوِيلِ, { فِي نَوْمهُمْ عَنْ اَلصَّلَاةِ - ثُمَّ أَذَّنَ بِلَالٌ, فَصَلَّى رَسُولُ اَللَّهِ - صلى الله عليه وسلم -كَمَا كَانَ يَصْنَعُ كُلَّ يَوْمٍ } رَوَاهُ مُسْلِمٌ [1] .
Narrated Abu Qatadah (RA) in a long Hadith about their (Sahaba) sleeping late past the time of Salat (prayer): Then Bilal proclaimed the Adhan and the Prophet (ﷺ) offered the prayer (while leading the Companions) as he used to do every day. [Reported by Muslim].
