Answered by Shaykh Faraz Rabbani
While leading Zuhr salah I forgot to recite surah after Fateha in second rakat. Then I recited the surah in third rakat and performed prostration of forgetfulness (sajda sahw). Was it correct or do I have to repeat salah and let others know, who were followers?
Walaikum assalam wa rahmatullah,
What you did was correct:
Reciting a sura or at least the extent of three short verses of the Qur’an after the Fatiha is necessary (wajib) in prayer. Leaving a necessary (wajib) action does not invalidate the prayer; when done forgetfully, one’s error must be rectified by performing forgetfulness prostrations.

And Allah alone gives success.
