English translation
6230. Narrated 'Abdullāh (bin Mas'ūd) رضي الله عنه: Whenever we offered Ṣalāt (prayer) with the Prophet ﷺ, we used to say : As-Salām be on Allāh from His worshippers, As-Salām be on Jibrīl (Gabriel), As-Salām be on Mikāel (Michael), As-Salām be on so-and-so. When the Prophet ﷺ finished his Ṣalāt (prayer), he faced us and said, "Allāh Himself is As-Salām (Peace), so when one sits in the Ṣalāt (prayer) (sitting posture for At-Taḥiyāt), one should say, 'At-Taḥiyātullāhi waṣ-ṣalawātu, waṭ-taiyibātu. As-salāmu 'alaika aiyuhan-Nabīyyu wa raḥmatu-llāhi wa barakātuhu. As-Salāmu 'alainā wa 'alā ibādillah-iṣ-ṣāliḥin,(1) for if he says that, it will be for all the pious slaves of Allāh in the heavens and the earth. (Then he should say), 'Ash-hadu an lā ilāha illallāhu wa ash-hadu anna Muḥammadan 'abduhū wa Rasūluhu,'(2) and then he can choose whatever speech (i.e., invocation) he wishes." [See Vol. 1, Hadīth No. 835]
