Narrated Ibn 'Umar and 'Aishah (RA):

Allah's Messenger (ﷺ) said: "Bilal calls for prayer when it is still night, so eat and drink till Ibn Umm Maktum calls for prayer." And he (Ibn Umm Maktum) was a blind man who did not call for a prayer until he was told: "It is morning time, it is morning time." [Agreed upon]. There is an Idraj in its last part.

وَعَنْ اِبْنِ عُمَرَ, وَعَائِشَةَ قَالَا: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ إِنَّ بِلَالاً يُؤَذِّنُ بِلَيْلٍ, فَكُلُوا وَاشْرَبُوا حَتَّى يُنَادِيَ اِبْنُ أُمِّ مَكْتُومٍ", وَكَانَ رَجُلاً أَعْمَى لَا يُنَادِي, حَتَّى يُقَالَ لَهُ: أَصْبَحْتَ, أَصْبَحْتَ } مُتَّفَقٌ عَلَيْهِ [1]‏ .‏ وَفِي آخِرِهِ إِدْرَاجٌ [2]‏ .‏
