This came in from a colleague.
A Sufi saint, on pilgrimage to Mecca, having completed the prescribed religious practices, knelt down and touched his forehead to the ground and prayed: “Allah! I have only one desire in life. Give me the grace of never offending you again.”
When the All-Merciful heard this he laughed aloud and said, “That’s what they all ask for. But if I granted everyone this grace, tell me, whom would I forgive?”
