Muwatta Imam Malik Book of Zakat, Hadith 39

Yahya related to me from Malik from Ibn Shihab from Sulayman ibn Yasar that the people of Syria said to Abu Ubayda ibn al-Jarrah, "Take zakat from our horses and slaves," and he refused. Then he wrote to Umar ibn al-Khattab and he (also) refused. Again they talked to him and again he wrote to Umar, and Umar wrote back to him saying, "If they want, take it from them and (then) give it back to them and give their slaves provision."
Malik said, "What he means, may Allah have mercy upon him, by the words 'and give it back to them' is, 'to their poor.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ أَهْلَ الشَّامِ، قَالُوا لأَبِي عُبَيْدَةَ بْنِ الْجَرَّاحِ خُذْ مِنْ خَيْلِنَا وَرَقِيقِنَا صَدَقَةً . فَأَبَى ثُمَّ كَتَبَ إِلَى عُمَرَ بْنِ الْخَطَّابِ فَأَبَى عُمَرُ ثُمَّ كَلَّمُوهُ أَيْضًا فَكَتَبَ إِلَى عُمَرَ فَكَتَبَ إِلَيْهِ عُمَرُ إِنْ أَحَبُّوا فَخُذْهَا مِنْهُمْ وَارْدُدْهَا عَلَيْهِمْ وَارْزُقْ رَقِيقَهُمْ . قَالَ مَالِكٌ مَعْنَى قَوْلِهِ رَحِمَهُ اللَّهُ وَارْدُدْهَا عَلَيْهِمْ يَقُولُ عَلَى فُقَرَائِهِمْ .
