Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) said: A man came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, my mount has been left behind on the way, so provide me with a mount." The Prophet (peace and blessings be upon him) said: "I do not have a mount to give you, but go to so-and-so; he will give you a mount." He went to him and he gave him a mount. Then the Messenger of Allah (peace and blessings be upon him) said: "The one who guides to good is like the one who does it, or the one who acts upon it."
