Khunash San'ani says that we fought jihad with the people of a town called Jarbah in the west along with Hazrat Ruwaifi' (may Allah be pleased with him). He distributed it among us, then he stood up to deliver a sermon and said: It is not lawful for any man who believes in Allah and the Last Day to irrigate another man's field (wife) with his "water" until she has her "days" (menstruation). Because I heard the Prophet (peace and blessings of Allah be upon him) say: It is not lawful for any person to irrigate another's offspring with his "water."
