Sayyiduna al-Hakam bin Umayr (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) used to teach us: "When you stand for prayer, raise your hands, and let them be level with your ears; then say: 'Allahu akbar, Subhanaka Allahumma wa bihamdika, wa tabaraka ismuka, wa ta'ala jadduka, wa la ilaha ghayruka' (O Allah, You are free of all imperfection, and all praise is Yours; blessed is Your name, exalted is Your majesty, and there is no god besides You). And if you suffice with the takbir alone, that is enough for you as well."
