Yahya related to me from Malik from Urwa ibn Husayn from A'isha bint Qudama that her father said, "When I used to come to Uthman ibn Affan to collect my allowance he would ask me, 'Do you have any property on which zakat is due? 'If I said, 'Yes,' he would deduct the zakat on that property from my allowance, and if I said, 'No,' he would pay me my allowance (in full)."
أَنَّهُ قَالَ كُنْتُ إِذَا جِئْتُ عُثْمَانَ بْنَ عَفَّانَ أَقْبِضُ عَطَائِي سَأَلَنِي هَلْ عِنْدَكَ مِنْ مَالٍ وَجَبَتْ عَلَيْكَ فِيهِ الزَّكَاةُ قَالَ فَإِنْ قُلْتُ نَعَمْ أَخَذَ مِنْ عَطَائِي زَكَاةَ ذَلِكَ الْمَالِ وَإِنْ قُلْتُ لاَ دَفَعَ إِلَىَّ عَطَائِي
