Narrated 'Abdullah:

We used to participate in the holy battles led by Allah's Messenger (ﷺ) and we had nothing (no wives) with us. So we said, "Shall we get ourselves castrated?" He forbade us that and then allowed us to marry women with a temporary contract (2) and recited to us: -- 'O you who believe ! Make not unlawful the good things which Allah has made lawful for you, but commit no transgression.' (5.87)

Narrated `Abdullah:

We used to participate in the holy wars carried on by the Prophet (ﷺ) and we had no women (wives) with us. So we said (to the Prophet (ﷺ) ). "Shall we castrate ourselves?" But the Prophet (ﷺ) forbade us to do that and thenceforth he allowed us to marry a woman (temporarily) by giving her even a garment, and then he recited: "O you who believe! Do not make unlawful the good things which Allah has made lawful for you."

Abdullah (b. Mas'ud) reported: We were on an expedition with Allah's Messenger (ﷺ) and we had no women with us. We said: Should we not have ourselves castrated? He (the Holy Prophet) forbade us to do so He then granted us permission that we should contract temporary marriage for a stipulated period giving her a garment, and 'Abdullah then recited this verse: 'Those who believe do not make unlawful the good things which Allah has made lawful for you, and do not transgress. Allah does not like trangressers" (al-Qur'an, v. 87).
