Hadith 5:32
Abu Huraira reported God’s messenger as saying, “When any of you hears the summons to prayer while he has a vessel in his hand he should not lay it down till he finishes his drink.”* *This is interpreted as referring to the dawn prayer during Ramadan. Abu Dawud transmitted it.
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا سَمِعَ النِّدَاءَ أَحَدُكُمْ وَالْإِنَاءُ فِي يَدِهِ فَلَا يَضَعْهُ حَتَّى يَقْضِيَ حَاجَتَهُ مِنْهُ» . رَوَاهُ أَبُو دَاوُد
