It is narrated from Hanish Sana'ani, he says: We fought with Sayyiduna Ruwaifi' bin Thabit Ansari (may Allah be pleased with him) against the people of the village called Jarabbah in the Maghrib. He stood among us to address us and said: O people! I will tell you only what I heard from the Messenger of Allah (peace and blessings be upon him). On the day of Hunayn, he stood among us and said: It is not lawful for a servant who believes in Allah and the Last Day to water someone else's crop with his own water, that is, to have intercourse with a slave woman before ensuring she is not pregnant when buying a used slave woman; to sell the spoils of war before distribution; to take a riding animal from the spoils of the Muslims, ride it, make it weak, and then return it to the spoils; or to take a garment from the spoils of the Muslims, wear it, make it worn out, and then return it to the spoils. By forbidding watering someone else's crop, the Messenger of Allah (peace and blessings be upon him) meant that one should not establish intimate relations with captive women who may be pregnant before ensuring they are not pregnant.
