(a) 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 (peace and blessings be upon him)! I am worn out; give me a mount." The Messenger of Allah (peace and blessings be upon him) said: "I do not have one." A man said: "O Messenger of Allah! Shall I point out a man who will give him a mount?" He (peace and blessings be upon him) said: "The one who guides to good and the one who does it are equal in reward."
(b) In another narration, Abu Mu'awiyah said "my way has been cut off" instead of "I am worn out."
