If one forgets to sit in the first Qa'dah when performing 4 raka'rs Fardh Salaat, should one return to Qa'dah from Qiyaam?

Answer

If you are performing a four raka't Fardh Salaat, and in Qiyaam you realized that you did not sit for Qa'dah in the second raka't, you should continue with the Salaat, and not return to Qa'dah. You have to make Sajdah Sahw for this error.
