Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that the Messenger of Allah ﷺ said, "Bilal calls the adhan in the night, so eat and drink until Ibn Umm Maktum calls the adhan." Ibn Umm Maktum was a blind man who did not call the adhan until someone said to him, "The morning has come. The morning has come."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ بِلاَلاً يُنَادِي بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُنَادِيَ ابْنُ أُمِّ مَكْتُومٍ قَالَ وَكَانَ ابْنُ أُمِّ مَكْتُومٍ رَجُلاً أَعْمَى لاَ يُنَادِي حَتَّى يُقَالَ لَهُ أَصْبَحْتَ أَصْبَحْتَ
