Is it Prophet's sunnah to turn right and left to say asalamwaalaikum wa rahmatulla after prayer. Please clarify. As I am a convert, I chose religion of Islam by Allah's grace. Majority in India belong to sunni school of thought. They taught me to turn right and left to say asalamwaalaikum at last part in prayer but I saw in shia prayer they dont do it.

After you completely finish your prayer if you want to turn to right and left is fine.
