Abu Mas'ud al-Ansari told of a man who came to the Prophet and
said, “My camel has become jaded, so give me a mount.” On his replying that he had none, a man said, “Messenger of God, I can guide him
to one who will give him a mount.” God’s messenger then said, “He
who guides to what is good will have a reward equivalent to that of him
who does it.” Muslim transmitted it.
