"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  

"The Messenger of Allah ﷺ said: 'When Ibn Umm Maktum calls the Adhan, eat and drink, and when Bilal calls the Adhan, do not eat nor drink."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَذَّنَ ابْنُ أُمِّ مَكْتُومٍ فَكُلُوا وَاشْرَبُوا وَإِذَا أَذَّنَ بِلاَلٌ فَلاَ تَأْكُلُوا وَلاَ تَشْرَبُوا
