Musnad Ahmad 25:1014

'Abd al-Razzaq narrated to us, Isra'il informed us, from Simak, from 'Ikrimah, from Ibn 'Abbas, who said: It was said to the Prophet, may Allah bless him and grant him peace, when he finished from Badr: "The caravan is upon you; there is nothing else besides it." He said: Then al-'Abbas called out to him while he was a captive in his bonds: "It is not appropriate." He said: So the Prophet, may Allah bless him and grant him peace, said to him: "Why?" He said: "Because Allah has promised you one of the two parties, and He has already given you what He promised you."
