Explanation

Yazīd ibn al-Akhnas left some dirhams with a man in the mosque to give them in charity to the poor. His son Ma‘in came and took them, so Yazīd said to him: "I did not intend to spend these dirhams in charity on you." So they went to seek judgment from the Messenger of Allah (may Allah's peace and blessings be upon him) who said to them: "For you, Yazīd, is the reward of what you intended, because your charity reached a poor Muslim. So the reward is due to you for your intention. And for you, Ma‘in, is what you took, because you took it rightfully." His son was, indeed, from among those who deserved charity.
