The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 3156
'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 (may peace be upon him) has given me as spoil, and refused to return anything to them.
