1489. Narrated 'Abdullâh bin 'Umar رَضِيَ اللَّهُ عَنْهُمَا: 'Umar bin Al-Khaṭṭâb gave a horse in charity in Allâh's Cause, and later he saw it being sold in the market and intended to purchase it. Then he went to the Prophet ﷺ and asked his permission. The Prophet ﷺ said, "Do not take back what you have given in charity." (The subnarrator added,) "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.
