Sayyiduna Abdur Rahman bin Safwan, who faced great trials in Islam and was a friend of Sayyiduna Abbas, brought his father to the service of the Prophet (peace be upon him) on the day of the conquest of Makkah and said, "O Messenger of Allah! Take the pledge of migration from him." The Prophet (peace be upon him) refused and said that the command of migration is no longer in effect. Upon this, he went to Sayyiduna Abbas, who was serving water to the people, and said to him, "O Abu Fadl, I brought my father to the Prophet (peace be upon him) so that he would take the pledge of migration from him, but he refused." Hazrat Abbas got up with him without even taking his cloak and said, "O Messenger of Allah! You know what kind of relationship I have with this person. He brought his father to you so that you would take the pledge of migration from him, but you refused." The Prophet (peace be upon him) said, "The command of migration is no longer in effect." He said, "I implore you, please take his pledge." The Prophet (peace be upon him) then extended his blessed hand and said, "Come, I will fulfill my uncle's request, but the matter remains that the command of migration is no longer in effect."
