It was narrated from 'Alqamah bin Qais that 'Abdullah said:
"We used not to know what to say when we prayed, then the Messenger of Allah (ﷺ) taught us some eloquent and concise words. He said to us: 'Say: "At-tahiyyatu lillahi was-salawatu wat-tayyibat, as-salamu 'alaika ayyuhan-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu 'alaina wa 'ala 'ibad illahis-salihin, ashahdu an la illaha ill-Allah wa ashhadu anna Muhammadan 'abduhu wa rasuluhu (Allah compliments, prayers and pure words are due to Allah. Peace be upon you, O Prophet, and the mercy of Allah (SWT) and his blessings. Peace be upon us and upon the righteous slaves of Allah (SWT). I bear witness that none has the right to be worshipped except Allah and I bear witness that Muhammad is His slave and Messenger)." (One of the narrators) 'Ubaidullah said: "Zaid bin Hammad said, narrating from Ibrahim, that 'Alqamah said: 'I saw Ibn Mas'ud teaching us these words just as he taught us the Quran."
