Narrated `Abdullah bin Mas`ud: We used to say the greeting, name and greet each other in the prayer. Allah's Apostle heard it and said:--"Say, 'at-tahiyyatu lil-lahi was-salawatu wat-taiyibatu . Assalamu 'Alaika aiyuha-n-Nabiyu warahmatu- l-lahi wa-barakatuhu. _ Assalamu alaina wa-'ala 'ibadi-l-lahi as-salihin.. Ashhadu an la ilaha illa-l-lah wa ashhadu anna Muhammadan `Abdu hu wa Rasuluh. (All the compliments are for Allah and all the prayers and all the good things (are for Allah). Peace be on you, O Prophet, and Allah's mercy and blessings (are on you). And peace be on us and on the good (pious) worshipers of Allah. I testify that none has the right to be worshipped but Allah and that Muhammad is His slave and Apostle.) So, when you have said this, then you have surely sent the greetings to every good (pious) worshipper of Allah, whether he be in the Heaven or on the Earth . "

Narrated Shaqiq bin Salama: `Abdullah said, "Whenever we prayed behind the Prophet we used to recite (in sitting) 'Peace be on Gabriel, Michael, peace be on so and so. Once Allah's Apostle looked back at us and said, 'Allah Himself is As-Salam (Peace), and if anyone of you prays then he should say, at-Tahiyatu li l-lahi wa ssalawatu wa t-taiyibat. As-salamu `alalika aiyuha n-Nabiyu wa rahmatu l-lahi wa barakatuh. Assalamu `alaina wa `ala `ibadi l-lahi s-salihin. (All the compliments, prayers and good things are due to Allah; peace be on you, O Prophet, and Allah's mercy and blessings [be on you]. Peace be on us an on the pious subjects of Allah). (If you say that, it will reach all the subjects in the heaven and the earth). Ash-hadu al-la ilaha illa l-lah, wa ash-hadu anna Muhammadan `Abduhu wa Rasuluh. (I testify that there is no Deity [worthy of worship] but Allah, and I testify that Muhammad is His slave and His Apostle).

Narrated `Abdullah: When we prayed with the Prophet we used to say, "Peace be on Allah from His slaves and peace be on so and so." The Prophet said, "Don't say As-Salam be on Allah, for He Himself is As-Salam, but say, at-tahiyatu li l-lahi wa s-salawatu wa t-taiyibat. As-salamu `alaika aiyuha n-Nabiyu wa rahmatu l-lahi wa barakatuh. As-salamu `alaina wa `ala `ibadi l-lahi s-salihin. (If you say this then it will reach all the slaves in heaven or between heaven and earth). Ash-hadu al la-ilaha illa l-lah, wa ash-hadu anna Muhammadan `Abduhu wa Rasuluh.' Then select the invocation you like best and recite it." (See Hadith No. 794, 795 & 796).

Narrated `Abdullah: When we prayed with the Prophet we used to say: As-Salam be on Allah from His worshipers, As- Salam be on Gabriel, As-Salam be on Michael, As-Salam be on so-and-so. When the Prophet finished his prayer, he faced us and said, "Allah Himself is As-Salam (Peace), so when one sits in the prayer, one should say, 'at-Tahiyatu-li l-lahi Was-Salawatu, Wat-Taiyibatu, As-Salamu 'Alaika aiyuhan- Nabiyyu wa Rah-matul-iahi wa Barakatuhu, As-Salamu 'Alaina wa 'ala 'Ibadillahi assalihin, for if he says so, then it will be for all the pious slave of Allah in the Heavens and the Earth. (Then he should say), 'Ash-hadu an la ilaha illalllahu wa ash-hadu anna Muhammadan `Abduhu wa rasulu-hu,' and then he can choose whatever speech (i.e. invocation) he wishes " (See Hadith No. 797, Vol. 1).

Narrated Ibn Mas`ud: Allah's Apostle taught me the Tashah-hud as he taught me a Sura from the Qur'an, while my hand was between his hands. (Tashah-hud was) all the best compliments and the prayers and the good things are for Allah. Peace and Allah's Mercy and Blessings be on you, O Prophet! Peace be on us and on the pious slaves of Allah, I testify that none has the right to be worshipped but Allah, and I also testify that Muhammad is Allah's slave and His Apostle. (We used to recite this in the prayer) during the lifetime of the Prophet , but when he had died, we used to say, "Peace be on the Prophet."

Narrated `Abdullah: We used to say in the prayer: 'AsSalam be on Allah, As-Salam be on so-and so.' So one day the Prophet said to us, "Allah Himself is As-Salam; when anyone of you sits during his prayer, he should say: 'at-tah, iyyatu-li l-lahi,' up to 'As-Salihin,' (All the compliments are for Allah ...righteous people) for when he recites this, then he says his Salam to all the righteous people present in the heavens and on the earth. Then he should say, 'I testify that none has the right to be worshipped except Allah, and that Muhammad is His slave and His Apostle,' and then he can select whatever he likes to celebrate (Allah's) Praises."

Narrated `Abdullah: We used to pray behind the Prophet and used to say: "As-Salamu 'Al-Allah. The Prophet said, "Allah himself is As-Salam (Name of Allah), so you should say: 'at-Tahiyatu lil-laihi was- sala-watu wattaiyibatu, as-sallamu 'Alasia aiyuha-n-nabiyyu wa rahrmatu-l-lahi wa barak-atuhu, As-salamu 'alaina wa 'ala 'ibaldi-l-lahi as-salihin. Ashhadu an la ilaha il-lallah, wa ash-hadu anna Muhammadan `Abduhu wa rasuluhu."'
