Q: Since I became baaligh I have not read any salah. Now I want to make Qadha but I do not have the first 8 months of my periods marked, how must I make qadha? Will it be permissible to make full 8 months including the 10 days of my periods?
A: If you can remember more or less how many days your periods were, then exclude that number of days every month when making qadhaa. If you can’t remember, then make qadhaa for the full 8 months. Any extra qadhaa will be counted as nafl salah for which you will be rewarded.
