Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the Messenger of Allah (peace and blessings be upon him) finished the Battle of Badr, it was said to him: You should pursue this trade caravan, there is nothing else. So Sayyiduna Abbas (may Allah be pleased with him) called out to them, while he was in his bonds (he had been tied with rope), that it is not permissible for you, so he (the Prophet) said: Why (is it not permissible)? He (Abbas) said: Because Allah had promised you one of the two groups, and He has fulfilled for you what He had promised you.
