Q: When one or two Rakaats are missed of a four Rakaat Fard Salaat (behind an Imaam), how does one complete the missed Rakaat(s) – after Salaam? Do I have to read Surah Fatiha and another Surah or only Surah Fatiha?
A: 1 RAKAAT MISSED; The Muqtadi must recite Surah Faatiha and a Surah.
2 RAKAATS MISSED; The Muqtadi must recite in both Rakaats Surah Faatiha and a Surah.
3 RAKAATS MISSED; In the first Rakaat, the Muqtadi must recite Surah Faatiha and a Surah and then sit for Tashahhud. After Tashahhud, he must stand up for the second missed Rakaat and recite Surah Faatiha and a Surah. In the third missed Rakaat, he must recite Surah Faatiha only.
4 RAKAATS MISSED; In the first two Rakaats recite Surah Faatiha and a Surah. In the second two Rakaats recite only Surah Faatiha. (Shaami vol 2 pg. 346; Lebonon)
