Forgetting to recite a surah after Surah Faatihah in the last 2 rakaats of a Sunnah Muakkadah salaah
Q: If I am performing the 4 sunnah muakkadah of Zuhr Salaah, and in the last 2 rakaats, I forget to read a surah after Surah Faatihah, but I only realize that I left this out after I have completed my salaah, is my salaah valid or should I repeat it?
