I have missed 1 rakat of Isha’s Fard with jammat. So after the salam I stand up and go directly in to rukkah after reading ‘Alhamdulillah Hi-rabbil Aalameen’, and without reading any surrah after reading surah Fatiha. I forget to read and directly went into rukooh but I offered Sajdah Sahw. Is Namaz (Salat) Valid ?
