2775. Narrated Ibn 'Umar رضي الله عنهما: Once 'Umar gave a horse in charity to be used in Allāh's Cause (Jihād – holy fighting). It had been given to him by Allāh's Messenger ﷺ. 'Umar gave it to a man in charity to use it in Allāh's Cause Then 'Umar was informed that the man has put that horse for sale, so he asked Allāh's Messenger ﷺ whether he could buy it. Allāh's Messenger ﷺ replied, "You should neither buy nor take back what you have given in charity."
