There were to callers of adhan for the Messenger of Allah ﷺ: Bilal and Ibn Umm Maktum, the blind. The Messenger of Allah ﷺ said: "Bilal announces the adhan at night, so eat and drink until Ibn Umm Maktum announces adhan." And he ˹the narrator˺ said: "The ˹period˺ between their ˹adhans˺ was not more than this that one climbing down ˹from the place of adhan˺ and the other one climbing up."

كَانَ لِرَسُولِ اللَّهِ ﷺ مُؤَذِّنَانِ بِلاَلٌ وَابْنُ أُمِّ مَكْتُومٍ الأَعْمَى فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ بِلاَلاً يُؤَذِّنُ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمِّ مَكْتُومٍ قَالَ وَلَمْ يَكُنْ بَيْنَهُمَا إِلاَّ أَنْ يَنْزِلَ هَذَا وَيَرْقَى هَذَا

"The Messenger of Allah ﷺ said: 'Bilal calls the Adhan during the night, so eat and drink until Ibn Umm Maktum calls the Adhan." She said: "And there was no more between than the time it takes for one to come down and the other to go up."

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَذَّنَ بِلاَلٌ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمِّ مَكْتُومٍ قَالَتْ وَلَمْ يَكُنْ بَيْنَهُمَا إِلاَّ أَنْ يَنْزِلَ هَذَا وَيَصْعَدَ هَذَا

[Machine] Indeed, the Prophet ﷺ said, "Verily, Ibn Umm Maktum calls for the prayer at night, so eat and drink until Bilal calls for the prayer." And Bilal used to call for the prayer when he saw the dawn.

أَنَّ النَّبِيَّ ﷺ قَالَ «إِنَّ ابْنَ أُمِّ مَكْتُومٍ يُؤَذِّنَ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ بِلَالٌ» وَكَانَ بِلَالٌ يُؤَذِّنُ حِينَ يَرَى الْفَجْرَ

"The Messenger of Allah ﷺ said: 'Bilal calls the Adhan during the night, so eat and drink until Ibn Umm Maktum calls the Adhan." She said: "And there was no more between than the time it takes for one to come down and the other to go up." (Using translation from Nasāʾī 639)

قَالَ رَسُولُ اللهِ ﷺ «إِذَا أَذَّنَ بِلَالٌ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمَّ مَكْتُومٍ» قَالَتْ وَلَمْ يَكُنْ بَيْنَهُمَا إِلَّا أَنْ يَنْزِلَ هَذَا وَيَصْعَدَ هَذَا
