Muwatta Imam Malik Book of Zakat, Hadith 14

Yahya related to me from Malik that he had heard that A'isha, the wife of the Prophet ﷺ used to give the property of the orphans that were in her house to whoever would use it to trade with on their behalf.

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ ﷺ كَانَتْ تُعْطِي أَمْوَالَ الْيَتَامَى الَّذِينَ فِي حَجْرِهَا مَنْ يَتَّجِرُ لَهُمْ فِيهَا .
