Sahih Muslim Book 8, Hadith Number 3243.

Chapter: Temporary marriage and its prohibition for all times to come.

Abdullah (b. Mas’ud) reported: We were on an expedition with Allah’s Messenger (May peace be upon him) 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).
