“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.’”
“I attended the ‘Eid prayer with the Messenger of Allah (ﷺ). He led us in offering the ‘Eid prayer, then he said: ‘I have finished the prayer. Whoever wants to sit (and listen to) the sermon, then let him sit, and whoever wants to leave, then let him leave.’”
“The Messenger of Allah (ﷺ) passed judgement on the basis of a witness along with an oath by the claimant.
