If Imam in the second raka of some Jahri namaz does not recite Qira aloud for a time greater than the time to say SubhanAllah 3 times then will it be correct for a Muqtadi to say ‘Subhan Allah’ to bring it to the attention of Imam.
Answer
If the Imaam makes an error in Salaat, the Muqtadi should correct the Imaam
by saying, ‘Subhaanallah.’ (Maraaqiul Falaah pg.271)
and Allah Ta’ala Knows Best
