Sunan Ibn Majah, Hadith 3659 ⓘ
Abu Hurairah, may Allah be pleased with them, narrated that: Allah's Messenger said: "No child can compensate his father unless he finds a slave, and buys him and sets him free."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لاَ يَجْزِي وَلَدٌ وَالِدَهُ إِلاَّ أَنْ يَجِدَهُ مَمْلُوكًا فَيَشْتَرِيَهُ فَيُعْتِقَهُ " .
