We used to go on campaigns with the Messenger of Allah (ﷺ) and we had no wives with us. We said: O Messenger of Allah, can we not castrate ourselves? But he forbade us to do that. Then after that we were granted a concession allowing us to marry a woman in return for a garment for a limited time. Then `Abdullah recited: “O you who believe! Make not unlawful the Tayyihut (all that is good as regards foods, things, deeds, beliefs, persons) which Allah has made lawful to you, and transgress not. Verily, Allah does not like the transgressors" (al-Ma'idah 5:87].
