"Alqamah prayed five (rak'ahs) and when he said the taslim, Ibrahim bin Suwaid said : 'O Abu Shibl, you prayed five!' He said: 'Is that true, O odd-eyed one?' Then he prostrated two prostrations of forgetfulness, then he said: 'This is what the Messenger of Allah (ﷺ) did.'"
The Messenger of Allah (ﷺ) offered one of the afternoon prayers with five (rak'ahs), and it was said to him: "Has something been added to the prayer?" He said: 'Why are you asking?'

When he wanted to bow, he raised them (his hands) likewise, then placed his hands on his knees. When he raised his head from bowing, he raised them (his hands) likewise. When he prostrated he put his hands in the same position in relation to his head, then he sat up and lay his left foot on the ground. He placed his left hand on his left thigh and his right elbow on his right thigh, and made a circle with two of his fingers. And I saw him doing like this"- Bishr (one of the narrators) pointed with the forefinger of his right hand and made a circle with the thumb and middle finger.

He said; 'This'- and he held his right foot upright and lay his left foot on the ground, and placed his right hand on his right thigh and his left hand on his left thigh, and pointed with his forefinger."

"Before the tashahhud was enjoined, when we prayed we used to say: 'Peace (As-Salam) be upon Allah (SWT), pace be upon Jibril, peace be upon Mika'il.' The Messenger of Allah (ﷺ) said: 'Do not say this, for indeed Allah (SWT), the Mighty and Sublime, is As-Salam. Rather say: "At-tahiyyatu lillahi wasalawatu wat-tayibaat, as-salamu 'alaika ayah-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu 'alaina a 'ala ibad illahis-salihin, ashadu an la ilaha ill Allah, wa ashhadu anna Muhammadan 'abduhu wa rasuluhu. (All compliments, prayers and pure words 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 that none has the right to be worshipped except Allah, and I bear witness that Muhammad is His slave and messenger.)"
