قَالَ مَالِك : لَا بَأْسَ بِالتِّجَارَةِ فِي أَمْوَالِ الْيَتَامَى لَهُمْ إِذَا كَانَ الْوَلِيُّ مَأْمُونًا فَلَا أَرَى عَلَيْهِ ضَمَانًا
Imam Malik, may Allah have mercy on him, said: There is nothing wrong with trading with the wealth of an orphan when the guardian of the orphan is trustworthy and honest, and he will not be held liable if there is a loss.
