Arabic hadith text
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ اتَّجِرُوا فِي أَمْوَالِ الْيَتَامَى لاَ تَأْكُلُهَا الزَّكَاةُ ‏.‏
Translation

Yahya related to me from Malik that he had heard that Umar ibnal-Khattab said, "Trade with the property of orphans and then it willnot be eaten away by zakat."
