Sayyiduna Qatadah (may Allah be pleased with him) said: When the Messenger of Allah (peace and blessings be upon him) appointed me as leader over my people, I took his (peace and blessings be upon him) hand to bid him farewell, and the Messenger of Allah (peace and blessings be upon him) said: "May Allah make piety (taqwa) your provision for the journey, forgive your sin, and guide you towards good wherever you may be."
