Sayyiduna Iyas bin Abd Muzani, may Allah be pleased with him, who was among the companions of the Prophet (peace and blessings be upon him), said: Do not sell water, for I heard the Prophet (peace and blessings be upon him) forbidding the selling of water.
Amr bin Dinar said: I do not know which type of water he forbade selling. He said: They say, I do not know whether he forbade selling flowing water or drinking water.
