Assalamu Alaikum Wa Rahmatullah, Sometimes, when I am in a hurry at work (e.g. going into a meeting), I tend to restrict my sunnah prayers to its waajib elements. However, I had a query about: “Omitting the surah after Fatiha”. From my understanding, Shafi’is don’t consider it as an arkaan nor a waajib so sujud is not required. It will be really helpful if you could share the positions of the other 3 school e.g. if prostration of forgetfulness is required or not. InshaAllah, my intention is to pray a prayer that is valid according to all 4 schools even if time's running tight. Wassalam Jazakumullah Khair
