Question: In our Masjid, we have a Shafi’ee Imam since there are majority Shafi’ee followers here. Sometimes the Imam is absent. In his absence a Hanafi person leads the salaat. After the second ruku’ he waits for the Shafi’ee people to read their qunoot then goes into sajdah. Is this correct?
Answer: If the imam-e-naaib waits and does not recite anything during that time, everyone will have to repeat their salaat.
