It is narrated from Hazrat Abu Majliz (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) would come face to face with the enemy for battle, he would recite this supplication: "O Allah! You are my strength and my supporter. With Your help I attack, with Your help I advance, and with Your help I fight." O Allah! You alone are my strength and You alone are my helper. By Your strength I attack and pounce, and by Your strength alone I fight.
