It has been narrated on the authority of Abu Mas’ud al-Ansari رضي الله
عنه who said: A man came to the Messenger of Allah صلى الله عليه وسلم
and said: My riding beast has been killed, so give me some animal to
ride upon. He صلى الله عليه وسلم said: I have none with me. A man said:
Messenger of Allah صلى الله عليه وسلم , I can guide him to one who will
provide him with a riding beast. The Messenger of Allah صلى الله عليه
وسلم said: One who guides to something good has a reward similar to
that of its doer.
