Narrated from Sayyiduna Abu Mas'ud Ansari (may Allah be pleased with him) that a man came to the service of the Prophet (peace and blessings of Allah be upon him) and said, "My mount has become unable to walk, contrary to its usual habit, so please provide me with a mount." The Prophet (peace and blessings of Allah be upon him) said, "I do not have a mount, but go to such-and-such a person, perhaps he will give you a mount." So he went to that person, and he gave him a mount. He came back and informed the Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) said, "Whoever guides to a good deed, for him is a reward equal to that of the one who does it."
