Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that when the Messenger of Allah, peace and blessings be upon him, would begin the prayer, he would recite: «سبحانك اللهم وبحمدك وتبارك اسمك، وتعالى جدك ولا إله غيرك» "O Allah! You are Pure with Your praises, blessed is Your name, exalted is Your status, and there is no true deity except You."
