It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "There is appointed for each one of you a companion from among the devils." The people asked: "O Messenger of Allah! Is this also the case with you?" He replied: "Yes! But Allah has helped me and my devil has submitted to me."
