Abu Hurairah reported,

The Messenger of Allah ﷺ said, "A child cannot repay his parent unless he finds him enslaved, then buys him and sets him free."In another wording, "A child cannot repay his father."

عن أبي هريرة قال

قال رسول الله ﷺ: لا يجزي ولد- والدا إلا أن يجده مملوكا فيشتريه فيعتقه. وفي لفظ: لا يجزي ولد والده.
