Who should lead the salaah as imam?

“A Ma’zoor person making Imaamat of people who are not categorized as Ma’zoor (in fact they are in a perfect state of Tahaarah) is incorrect. Yes, a Ma’zoor may lead another Ma’zoor in Salaah as long as the both are afflicted with the same llness/problem.”

“The Imaamat of an Imaam that sits on a chair and leads the Salaah is not valid. In the queried scenario, the Imaam will be performing Sajdah by indication, whereas the Muqtadis (followers behind the Imaam) will be performing Sajdah in a perfect manner (i.e. by bowing down fully in the posture of Sajdah).”

“In principle, the resident of the house will have the right to lead the salah even in the presence of those who are more qualified in Shariah than him on condition the Imaamat of the host will not be makrooh for e.g.”

“It is not permissible for a Muqtadi (who can perform Sajdah on the ground) to follow an Imam that cannot perform Sajdah on the ground. However, it is valid to pray behind an Imam who is sitting down if the Imam can prostrate on the ground.”
