Najafi Q&A: Final Salutations in Prayer (Tasleem)

Answer

In the name of Allah, be informed, my son, the first tasleem "assalamu alaik ya ayiuha alnabi wa rahmatullah wa barakatuh" is recommended and do not void the prayer. As for the second tasleem " assalamu alaina wa ala Ibadillah assaliheen", it is the obligatory one with which prayers are completed. The third tasleem "assalamu alaikum wa rahmatullahi wa barakatuh" is recommended. Allah knows best.
