it would be aapreciated if you could answer my question
as i wish to perform my qaza namaazes from the time that it had become compulsary how would one calculate the amount of salaahs missed as one can not remember which salaahs have not been performed.wht intention would one make would it be for each year or what .and how many rakaats would have to be performed for each salaah.
Draw on estimate. Sit dowm, calculate from the age of puberty hor Fajr, your performed, do this for every Salaat, including Witr. Then start from one Salaat, perform and keep reducing. Complete one Salaat at a time. See for 'Qaza Salaat' on our site.
