The Prophet (ﷺ) said: The supplier of the people is the last (man) to drink.
Sunan Abi Dawud Book 27, Hadith 57
← Previous Hadith The Prophet (ﷺ) went to visit a man of the Ansar accompanied by one of his Companions who was watering his garden. The Messenger of Allah(ﷺ) said: If you have any water which has remained over night in a skin (we should like it), or shall sip (from a streamlet).

Sunan Abi Dawud Book 27, Hadith 56 Next Hadith → 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.
