Sunan Ibn Majah Book 5, Hadith 99
“The Messenger of Allah (ﷺ)
addressed us and explained the Sunnah for us, and he taught us our
prayer. He said: ‘When you perform prayer, and you are sitting, let
the first thing you say be: At-Tahiyyatut-tayyibatus-salawatu lillah;
as-salamu ‘alayka ayyuhan-Nabiyyu wa rahmatullahi wa barakatuhu;
as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la
ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa Rasuluhu (All
compliments, good words and prayers are due to Allah; peace be upon
you, O Prophet, and the mercy of Allah and His blessings; peace be
upon us and upon the righteous slaves of Allah. I bear witness that
none has the right to be worshipped but Allah and I bear witness that
Muhammad is His slave and Messenger). Seven phrases which are the
greeting of the prayer.’”
“The Messenger of Allah (ﷺ) used to teach us the Tashah-hud as he used to teach us a Surah of the Qur’an. He used to say: ‘At-Tahiyyatul-Mubarakatus salawatut-tayyibatu lillah; As-salamu ‘alayka ayyuhan-Nabiyyu wa rahmatullahi wa barakatuhu; as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa Rasuluhu (All blessed compliments and good prayers are due to Allah; peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped but Allah and I bear witness that Muhammad is His slave and Messenger).’”
“The Messenger of Allah (ﷺ) used to teach us the Tashah-hud as he used to teach us a Surah from the Qur’an: ‘Bismillahi wa Billahi; at-tahiyyatu lillahi was-salawatu wat-tayyibatu lillahi; as-salamu ‘alayka ayyuhan- Nabiyyu wa rahmatullahi wa barakatuhu; as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa rasuluhu. As’alu Allahal-jannah, wa a’udhu billahi minannar (In the name of Allah and by the grace of Allah. All compliments are due to Allah and all prayers and good words are due to Allah. Peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped but Allah and I bear witness that Muhammad is His slave and Messenger. I ask Allah for Paradise and I seek refuge with Allah from the Fire).’”
