Animals, property, gold and silver as endowments

قَالَ الزُّهْرِيُّ فِيمَنْ جَعَلَ أَلْفَ دِينَارٍ فِي سَبِيلِ اللَّهِ، وَدَفَعَهَا إِلَى غُلاَمٍ لَهُ تَاجِرٍ يَتْجُرُ بِهَا، وَجَعَلَ رِبْحَهُ صَدَقَةً لِلْمَسَاكِينِ وَالأَقْرَبِينَ، هَلْ لِلرَّجُلِ أَنْ يَأْكُلَ مِنْ رِبْحِ ذَلِكَ الأَلْفِ شَيْئًا، وَإِنْ لَمْ يَكُنْ جَعَلَ رِبْحَهَا صَدَقَةً فِي الْمَسَاكِينِ قَالَ لَيْسَ لَهُ أَنْ يَأْكُلَ مِنْهَا.Az-Zuhri was asked, "If somebody founds an endowment of one thousand Dinar and gives the sum to his boy who is a trader to invest it in business and declares that the profit of the money will be given in charity to the poor and the relatives, does the founder have the right to use anything of the profit of the one thousand Dinar? And if he does not assign its profit to the poor?" Az-Zuhri said, "He does not have the right to use anything of it (i.e., in either case)."
