وَعَنْ عُمَرَ رضى الله عنه
قَالَ: «حَمَلْتُ عَلَى فَرَسٍ فِي سَبِيلِ اَللَّهِ، فَأَضَاعَهُ صَاحِبُهُ، فَظَنَنْتُ أَنَّهُ بَائِعُهُ بِرُخْصٍ، فَسَأَلْتُ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ ذَلِكَ. فَقَالَ: «لَا تَبْتَعْهُ، وَإِنْ أَعْطَاكَهُ بِدِرْهَمٍ …» اَلْحَدِيثَ
I provided a man with a horse to ride in Allah’s Cause, but as he did not look after it well, I thought he would sell it at a cheap price. I therefore asked the Messenger of Allah (sallallahu alayhi wa sallam) about that and he said, “Do not buy it even if he gives it to you for a Dirham…” The narrator reported the rest of the Hadith.
