Humayd bin Hilal (may Allah have mercy on him) narrates from a Bedouin of his people (may Allah be pleased with him) that he said: I came to the Messenger of Allah (peace and blessings be upon him) while he was delivering a sermon, and I said: O Messenger of Allah! Teach me. At the end of what I memorised was that he (peace and blessings be upon him) said: "Whenever you leave something out of fear of Allah, Allah gives you in its place something better than it."
