`Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that some people from the Ansar sought permission from the Messenger of Allah (peace and blessings be upon him), saying, "O Messenger of Allah! Allow us to waive the ransom of our nephew, Abbas bin Abdul Muttalib (may Allah be pleased with him)." So the Prophet (peace and blessings be upon him) said: "Do not leave even a single dirham from him."
