Narrated Jabir (may Allah be pleased with him): It never happened that anything was asked from the Prophet (peace and blessings of Allah be upon him) and he said: "No (I will not give it)."

Sayyiduna Anas (may Allah be pleased with him) says: I served the Prophet Muhammad (peace and blessings be upon him) for ten years. The Prophet (peace and blessings be upon him) never even said "Uff" to me, nor ever said: "Why did you do this?" or "Why did you not do this?"
