I've a question regarding namaz e shab. Sometime back I heard one of the moulana talking about namaz e shab can be prayed before going to bed (before midnight) if you cannot wake up before fajr time. Also he said if you cannot pray the 11 rakah, you can pray 3 rakah ( 2 rakah shifa namaz and 1 vitr and read the other duas one time each). Please let me know.
