It was narrated from ‘Amir bin Sa"d that

Sa"d went to his fortress in al-"Aqeeq, where he found a slave hitting a tree to make its leaves fall or cutting it down, so he stripped him of his belongings. When Sa"d returned, the owners of the slave came and asked him to return what he had taken from their slave. He said: “Allah forbid that I should return something that the Messenger of Allah (ﷺ) granted me of booty”, And he refused to return it to them.
