What did the Prophet Muhammad (saw) say about the Mut'a (temporary marriage) that was allowed to the people?
 Narrated Jabir bin `Abdullah and Salama bin Al-Akwa`:                     While we were in an army, Allah's Apostle came to us and said, "You have been allowed to do the Mut'a (marriage), so do it." Salama bin Al-Akwa` said: Allah's Apostle's said, "If a man and a woman agree (to marry temporarily), their marriage should last for three nights, and if they like to continue, they can do so; and if they want to separate, they can do so." I do not know whether that was only for us or for all the people in general. Abu `Abdullah (Al-Bukhari) said: `Ali made it clear that the Prophet said, "The Mut'a marriage has been cancelled (made unlawful).
