Sunan Ibn Majah Book 5, Hadith 115
“Ali led us in prayer on the day
of
(the battle of) the Camel, in a way that reminded us of the prayer
of
the Messenger of Allah (ﷺ). Either we had forgotten it or we had
abandoned it. He said the Salam to his right and to his left.”
“The Messenger of Allah (ﷺ) used to say the Salam to his right and to his left, until the whiteness of his cheek could be seen (saying): ‘As-salamu ‘alaikum wa rahmatullah, as-salamu ‘alaikum wa rahmatullah.’”
‘Abdul-Muhaimin bin ‘Abbas bin Sahl bin Sa’d As-Sa’idi narrated from his father, from his grandfather, that the Messenger of Allah (ﷺ) said one Taslim to the front.
