Hadith 638
Chapter 9: Two Mu'adhdhins In One Masjid - كتاب الأذان
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " إِنَّ بِلاَلاً يُؤَذِّنُ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى تَسْمَعُوا تَأْذِينَ ابْنِ أُمِّ مَكْتُومٍ " .
It was narrated from Salim, from his father, that the Prophet (S.A.W) said:
"Bilal calls the Adhan during the night, so eat and drink until you hear Ibn Umm Maktoom calling the Adhan."
