«إخوانكم خولكم جعلهم الله قنية تحت أيديكم فمن كان أخوه تحت يده فليطعمه من طعامه وليلبسه من لباسه ولا يكلفه ما يغلبه فإن كلفه ما يغلبه فليعنه»
The Prophet (peace and blessings be upon him) said:
"Your servants are your brothers; Allah Almighty has made them your property and placed them under your authority. So whoever has his brother under his authority, let him feed him from what he himself eats, clothe him from what he himself wears, and not burden them with work beyond their strength; and if he does burden them with more than their strength, then let him help them (in that work)."
