Chapter 97: Oneness, Uniqueness of Allah (Tawheed)
Narrated 'Abdullah: We used to pray behind the Prophet (ﷺ) and used to say: "As-Salamu 'Al-Allah. The Prophet (ﷺ) said, "Allah
himself is As-Salam (Name of Allah), so you should say: 'at-Tahiyatu lil-lahi was-sala-watu wattaiyibatu,
as-salamu 'alaika aiyyuha-n-nabiyyu wa rahmatu-l-lahi wa barakatuhu, as-salamu 'alaina
wa 'ala 'ibadi-l-lahi as-salihin. Ashhadu an la ilaha il-lallah, wa ash-hadu anna Muhammadan
'abduhu wa rasuluhu."'
