Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ قَالَ سَمِعْتُ الْقَاسِمَ عَنْ عَائِشَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ بِلَالًا يُؤَذِّنُ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمِّ مَكْتُومٍ قَالَتْ فَلَا أَعْلَمُهُ إِلَّا كَانَ قَدْرَ مَا يَنْزِلُ هَذَا وَيَرْقَى هَذَا.
English Translation
The Prophet (peace be upon him) said: "Bilal calls the adhan during the night, so eat and drink until Ibn Umm Maktum calls the adhan." She said: "The time between them was only as long as it takes for one to descend and the other to ascend."
