Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّ عُمَرَ رَضِيَ اللَّهُ تَعَالَى عَنْهُ حَمَلَ عَلَى فَرَسٍ فَأَعْطَاهَا عُمَرُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِيَحْمِلَ عَلَيْهَا رَجُلًا فَأُخْبِرَ عُمَرُ أَنَّهُ قَدْ وَقَفَهَا يَبِيعُهَا قَالَ فَسَأَلَ عَنْ ذَلِكَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَبْتَاعُهَا قَالَ لَا تَبْتَعْهَا وَلَا تَعُدْ فِي صَدَقَتِكَ.
English Translation
Yahya narrated to us, from 'Ubayd Allah - Nafi' informed me - from Ibn 'Umar, that 'Umar, may Allah Almighty be pleased with him, donated a horse to be ridden in Allah's cause. 'Umar gave it to the Messenger of Allah, peace and blessings be upon him, so that he might let a man ride it. Then 'Umar was informed that the man had left it standing for sale. He said: So he asked the Prophet, peace and blessings be upon him, about buying it back. He said: 'Do not buy it, and do not take back your charity.'
