حَدَّثَنَا يَحْيَی بْنُ بُکَيْرٍ حَدَّثَنَا اللَّيْثُ عَنْ عُقَيْلٍ عَنْ ابْنِ شِهَابٍ عَنْ سَالِمٍ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا کَانَ يُحَدِّثُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ تَصَدَّقَ بِفَرَسٍ فِي سَبِيلِ اللَّهِ فَوَجَدَهُ يُبَاعُ فَأَرَادَ أَنْ يَشْتَرِيَهُ ثُمَّ أَتَی النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَأْمَرَهُ فَقَالَ لَا تَعُدْ فِي صَدَقَتِکَ فَبِذَلِکَ کَانَ ابْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا لَا يَتْرُکُ أَنْ يَبْتَاعَ شَيْئًا تَصَدَّقَ بِهِ إِلَّا جَعَلَهُ صَدَقَةً
صحیح بخاری · Hadith 1489
Narrated `Abdullah bin `Umar: `Umar bin Al-Khattab gave a horse in charity in Allah's Cause and later he saw it being sold in the market and intended to purchase it. Then he went to the Prophet and asked his permission. The Prophet said, "Do not take back what you have given in charity." For this reason, Ibn `Umar never purchased the things which he had given in charity, and in case he had purchased something (unknowingly) he would give it in charity again.
