Sayyiduna Ali bin Taliq (may Allah be pleased with him) narrates: A Bedouin came to the service of the Noble Prophet (peace and blessings be upon him) and said: We live in a land that is barren and water is scarce. Sometimes a little wind passes from one of us and water becomes less (so what should we do)? The Noble Prophet (peace and blessings be upon him) said: When wind passes from anyone, he should perform ablution, and do not have intercourse with women in their back passage. Indeed, Allah is not shy of stating the truth.
