Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with him) used to stand on the pulpit and teach the people the tashahhud as narrated from the Prophet (peace and blessings be upon him): "All verbal, physical and financial acts of worship are for Allah. Peace be upon you, O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no true god except Allah, and I bear witness that Muhammad (peace and blessings be upon him) is His servant and His Messenger."
