Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) narrates that he gave a horse in the way of Allah. The Messenger of Allah (peace and blessings be upon him) gave that horse to a man. That man put the horse up for sale, so Sayyiduna Umar (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) and asked: Should I buy the horse which I gave in the way of Allah? The Prophet (peace and blessings be upon him) said: Do not buy it, and do not take back your charity.
