950. hadíth
وَ فِي رِوَايَةِ اَلْمُثَنَّى عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "إِنْ طَلَبَ اَلَّذِي رَبَّاهُ بِنَفَقَتِهِ وَ كَانَ مُوسِراً رَدَّ عَلَيْهِ وَ إِنْ لَمْ يَكُنْ مُوسِراً كَانَ مَا أَنْفَقَ صَدَقَةً".
In the narration of Al-Muthanna, from Abu Abdullah (a.s): "If the one who raised the abandoned child demands repayment for his expenses and he (the child) is financially capable, he must repay him. However, if he is not financially capable, then what was spent is considered charity."
