Some questions regarding salams in prayer:
In the name of Allah, Most Compassionate, Most Merciful,
Wa Alaikum Assalam wa Rahmatullah
1) Does the muqtadi also do the final salams in salat al-janazah?
Yes, it is wajib for the imam and follower (muqtadi) to make the final salams in the Janaza prayer. [Nur al-Idah]
2) If the imam needs to make sajdat as-sahw does the muqtadi also give salams to the right (only) with the imam before they go into their sajdahs?
Yes, it is sunna to make one tasleem to the right before going into the forgetfulness prostration (sujud sahw) for the imam and follower.
And Allah knows best
