Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates that (regarding taking off the Ihram after performing Umrah) there was much discussion among the people. We had come only with the intention of Hajj, until only a few days were left to take off the Ihram, then the Messenger of Allah (peace be upon him) ordered us to take off the Ihram (after performing Umrah). (We began saying among ourselves) Will any one of us go to Arafah (for Hajj) in such a state that drops of semen are dripping from his private part? When the Messenger of Allah (peace be upon him) came to know of these things, he stood up to deliver a sermon and said: "O people, I swear by Allah, do you know that I, by Allah, know Allah's commands better than all of you and fear Him more than all of you. If I had known earlier what I came to know later in this matter, I would not have brought the sacrificial animal with me and I too would have taken off the Ihram (after performing Umrah) like the rest of the people. Therefore, whoever does not have a sacrificial animal should fast three days here and seven days after returning home, and whoever finds a sacrificial animal should offer the sacrifice. Thus, we used to slaughter one camel on behalf of seven people."
