When you are praying in every Salah, when do you read a different Surah after Fatiha? For example, in Fajr, there is two rakats so you read Fatiha AND another Surah in both rakats. What about the other salahs?
What is For Dhuhr and Asr and Isha, you read Fatiha and another Surah in the first two rakats, then only Fatiha in the last two rakats. For Maghrib, you read Fatiha and another Surah only for the first two rakats, then for the last raka, you read only Fatiha.
