Chapter - Section 1
وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «إِن بِلَالًا يُؤذن بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُنَادِيَ ابْنُ أُمِّ مَكْتُوم» ثمَّ قَالَ: وَكَانَ رَجُلًا أَعْمَى لَا يُنَادِي حَتَّى يُقَالَ لَهُ: أَصبَحت أَصبَحت
Ibn ‘Umar reported God’s Messenger as saying, “Bilal summons to prayer when it is still night, so eat and drink till Ibn Umm Maktum makes the summons.” He added that Ibn Umm Maktum was a blind man who did not make the summons till someone said to him, “The morning has come, the morning has come.” (Bukhari and Muslim.)
