Compiled by Imam Yahya ibn Sharaf al-Nawawi
عَنْ أَبِي هُرَيْرَةَ رضي الله عنه، قَالَ: قَالَ رَسُولُ الله صلى الله عليه وسلم "لاَ يَجْزِي وَلَدٌ وَالِدًا إِلاَّ أَنْ يَجِدَهُ مَمْلُوكًا فَيَشْتَرِيَهُ فَيُعْتِقَهُ" ((رواه مسلم)).
Messenger of Allah (ﷺ) said, "No son can repay (the kindness shown by his father) unless he finds him a slave and buys him and emancipates him".[Muslim].
