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  

[Machine] The Prophet (peace and blessings be upon him) said, "If Ibn Umm Maktum or Bilal calls for the evening prayer, then continue eating and drinking until Bilal or Ibn Umm Maktum calls for the prayer. It was only that one of them would give the call to prayer while the other would ascend and we would take his hand and say, 'You are still in a state of fasting until we have finished suhoor (pre-dawn meal).' "  

إِنَّ النَّبِيَّ ﷺ قَالَ إِنَّ ابْنَ أُمِّ مَكْتُومٍ أَوْ بِلَالًا يُنَادِي بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُنَادِيَ بِلَالٌ أَوْ ابْنُ أُمِّ مَكْتُومٍ فَمَا كَانَ إِلَّا أَنْ يُؤَذِّنَ أَحَدُهُمَا وَيَصْعَدَ الْآخَرُ فَنَأْخُذَهُ بِيَدِهِ وَنَقُولَ كَمَا أَنْتَ حَتَّى نَتَسَحَّرَ  

[Machine] The Messenger of Allah ﷺ said, "Indeed, Bilal gives the call to prayer at night, so eat and drink until Ibn Umm Maktum gives the call to prayer. We used to detain Ibn Umm Maktum from the call to prayer, and we would say, 'Stay as you are until we eat our pre-dawn meal (Suhoor),' and there was nothing between their calls except for him descending while the other ascends, like this."  

رَسُولُ اللهِ ﷺ إِنَّ بِلَالًا يُؤَذِّنُ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمِّ مَكْتُومٍ وَكُنَّا نَحْبِسُ ابْنَ أُمِّ مَكْتُومٍ عَنِ الْأَذَانِ فَنَقُولُ كَمَا أَنْتَ حَتَّى نَتَسَحَّرَ وَلَمْ يَكُنْ بَيْنَ أَذَانِهِمَا إِلَّا أَنْ يَنْزِلَ هَذَا وَيَصْعَدَ هَذَا هَكَذَا
