However I did make it up by doing Qadhaa. But i didn’t know that one has to do the Qadhaa of the witr salaah as they are Waajib. I can not recall how often this happened. What do I do. Is it obligatory upon me to make them up or not?
Answer:
It is compulsory to make Qadhaa of Witr Salaat. You should apply your honest descrition and calculate the number of Witr Salaats you missed and make Qadhaa.
