Salam Aleykoum Brothers and sisters
I went to the mosque today for the morning prayer. During the 1rst rakat, after reciting the Al Fatiha, the Iman began reciting a surat. We then went in Ruku and then he said "Allah Akbar", continued with the surat, went on second ruku (all in the first rakat) , came back from the ruku with all the necessary invocations and we then went on soujoud.
I am wondering if it is permissible and if yes; what surat is that?
Thank y'all very much in advance
