The Prophet ﷺ said: 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 fulfils his need. (Using translation from Abū Dāʾūd 2350)
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا سَمِعَ أَحَدُكُمُ النِّدَاءَ وَالْإِنَاءُ عَلَى يَدِهِ فَلَا يَضَعْهُ حَتَّى يَقْضِيَ حَاجَتَهُ مِنْهُ
