Ibn al-Firasi narrates that his father, Sayyiduna al-Firasi (may Allah be pleased with him), came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Shall I ask people (for help)? He (peace and blessings be upon him) said: "No, but if you must ask, then ask the righteous."
