Dreaming of hindu accepting islam

a molana said me that if your first rakat is missed when you are praying with jamat, when you are making the first rakat after the salam of imam in fourth rakat you should not reciete thanah ( subahanakalahuma) before surah fatiha because the is no Qadha for sunah but some ulema of deoband told me you recite thanah. Who is write.
