When should the one who is serving water drink?

Narrated Abdullah ibn AbuAwfa:

The Prophet (ﷺ) said: The supplier of the people is the last (man) to drink.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي الْمُخْتَارِ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏

‏ سَاقِيَ الْقَوْمِ آخِرُهُمْ شُرْبًا ‏

‏ ‏.‏

Anas b. Malik said:

The Prophet (ﷺ) was brought milk that was mixed with water. A nomad Arab was on his right and Abu Bakr was on his left. He himself drank and gave it to the nomad Arab, and said: He who is on the right , then he who is on his right then he who is on his right.

حَدَّثَنَا الْقَعْنَبِيُّ عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ ‏

‏ الأَيْمَنَ فَالأَيْمَنَ ‏

‏ ‏.‏

Anas b.Malik said :

When the prophet (ﷺ) drank, he used to breathe three times in the course of a drink and say : It is more wholesome, thirst-quenching and healthier.

حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِي عِصَامٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا شَرِبَ تَنَفَّسَ ثَلاَثًا وَقَالَ ‏

‏ هُوَ أَهْنَأُ وَأَمْرَأُ وَأَبْرَأُ ‏
