A man reported,

We were with Abu Musa when some chicken was brought in. Among the group was a ruddy-complexioned man from Banu Taym Allah who looked like a freedman, and he did not come near.Abu Musa said to him, "Come closer, for I have seen the Messenger of Allah ﷺ eating it."The man replied, "I once saw it eating something filthy, so I found it disgusting and swore I would never eat it."Abu Musa said, "Come closer, and let me tell you about this. I came to the Prophet ﷺ with a group of the Ashari clan, asking him to provide us with mounts. He was dividing up some camels from the charity camels."Ayub said, "I think he said, and he was angry.""He said, 'No, by Allah, I will not provide you with mounts, and I have nothing to mount you on.' So we left. Then some captured camels were brought to the Messenger of Allah ﷺ, and he asked, 'Where are those Asharis?' We came to him, and he ordered that five fine camels with white humps be given to us.We set off, and I said to my companions, 'We came to the Messenger of Allah ﷺ asking for mounts, and he swore he would not provide us with any. Then he sent for us and gave us mounts. The Messenger of Allah ﷺ must have forgotten his oath. By Allah, if we take advantage of the Messenger of Allah's ﷺ forgetfulness about his oath, we will never prosper. Let us go back to the Messenger of Allah ﷺ and remind him of his oath.'So we went back to him and said, 'Messenger of Allah, we came to you asking for mounts, and you swore you would not provide us with any. Then you gave us mounts. We realized,' or, 'we thought that you had forgotten your oath.'He ﷺ said, 'Go on your way, for it is Allah who has provided you with mounts. By Allah, if Allah wills, I never swear an oath and then see something better than it without doing what is better and releasing myself from the oath.'"
