Muwatta Malik, Book 17, Hadith 610 (In-Book) ⓘ

Yahya related to me from Malik that he had heard that one of the administrators of Umar ibn Abd al-'Aziz wrote to him mentioning that a man had refused to pay zakat on his property. Umar wrote to the administrator and told him to leave the man alone and not to take any zakat from him when he took it from the other muslims. The man heard about this and the situation became unbearable for him, and after that he paid the zakat on his property. The administrator wrote to Umar and mentioned that to him, and Umar wrote back telling him to take the zakat from him.

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَامِلاً، لِعُمَرَ بْنِ عَبْدِ الْعَزِيزِ كَتَبَ إِلَيْهِ يَذْكُرُ أَنَّ رَجُلاً مَنَعَ زَكَاةَ مَالِهِ فَكَتَبَ إِلَيْهِ عُمَرُ أَنْ دَعْهُ وَلاَ تَأْخُذْ مِنْهُ زَكَاةً مَعَ الْمُسْلِمِينَ قَالَ فَبَلَغَ ذَلِكَ الرَّجُلَ فَاشْتَدَّ عَلَيْهِ وَأَدَّى بَعْدَ ذَلِكَ زَكَاةَ مَالِهِ فَكَتَبَ عَامِلُ عُمَرَ إِلَيْهِ يَذْكُرُ لَهُ ذَلِكَ فَكَتَبَ إِلَيْهِ عُمَرُ أَنْ خُذْهَا مِنْهُ ‏.‏
