Abdullah bin Zubayr reported,

After every prayer, once he had given the closing salutation, he would say, "There is no god but Allah, alone, with no partner. His is the dominion and His is the praise, and He has power over all things. There is no might and no power except through Allah. There is no god but Allah, and we worship none but Him. His is every favor, His is every bounty, and His is the finest praise. There is no god but Allah, and we devote our religion sincerely to Him, however much the disbelievers may hate it."The narrator added, "The Messenger of Allah ﷺ used to proclaim Allah's oneness with these words after every prayer."
