From Sahih Muslim (Hadith 3320):
Amir b. Sa'd reported that Sa'd rode to his castle in al-'Aqiq and found a slave cutting down the trees, or beating off their leaves, so he stripped him off his belongings. When Sa'd returned, there came to him the masters of the slave and negotiated with him asking him to return to their slave or to them what he had taken from their slave, whereupon he said:God forbid that I should return anything which Allah's Messenger (ﷺ) has given me as spoil, and refused to return anything to them
