Musannaf Ibn Abi Shaybah 22228 — Selling and buying water

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: There are three wretched people to whom Allah Almighty will not speak on the Day of Resurrection: first, a man who has surplus water but does not give it to a traveller; second, a man who swears a false oath after Asr in order to sell his goods; third, a man who pledges allegiance at the hand of the leader (imam): if he gives him something, he fulfils the pledge, and if he gives him nothing, he does not fulfil it.
