Imam Malik's Muwatta, Chapter: Prayer

Yahya related to me from Malik from Ibn Shihab from Urwa ibn az-Zubayr from Abd ar-Rahman ibn Abd al-Qari that he heard Umar ibn al-Khattab say, while he was teaching people the tashahhud from the mimbar, "Say, Greetings belong to Allah. Pure actions belong to Allah. Good words and prayers belong to Allah. Peace on you, Prophet, and the mercy of Allah and His blessings. Peace be upon us and on the slaves of Allah who are salihun. I testify that there is no god except Allah. And I testify that Muhammad is His slave and His messenger." 'At-tahiyatu lillah, az-zakiyatu lillah, at-tayibatu wa's-salawatu lillah. As-salamu alayka ayyuha'nnabiyyu wa rahmatu'llahi wa barakatuhu. As-salamu alayna wa ala ibadi'llahi s-salihin. Ash-hadu an la ilaha illa 'llah wa ash-hadu anna Muhammadan abduhu wa rasuluh."
