The one who serves water to others should be the last one to drink from it
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، وَسُوَيْدُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ رَبَاحٍ، عَنْ أَبِي قَتَادَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " سَاقِي الْقَوْمِ آخِرُهُمْ شُرْبًا " .
It was narrated from Abu Qatadah that the Messenger of Allah (ﷺ) said: “The oen who serves water to others should be the last one to drink from it.”
