Qadhaa is made only for Fardh and Witr Salaats.
In calculation, there will be six (6) Salaats per day, one hundred and eighty (180) Salaats per month, two thousand, one hundred and sixty (2160) Salaats per year. Calculate the number of missed Salaats from the time of Buloogh (maturity). If one is unable to calculate the actual number of missed Salaats, due to not having any records, then he/she should apply his/her honest discretion in calculating the missed Salaats.
It is not permissible to give Fidyah (monetary compensation) for the missed Salaats if one is able to fulfil the Qadhaa Salaats. The Fidya for each missed Salaat is the same as Sadaqatul Fitr (approx. R7.00). The approximate amount for the missed Salaats for one year will be (approx. R15,000). A bequest should be made during one’s lifetime to pay the Fidya for the unfulfilled Qadhaa Salaats from one third of one’s estate after fulfillment of debts.
Thank Allah Ta’ala for giving you the concern to fulfil the missed Salaats. How will one face Allah Ta’ala on the day of Qiyaamat should he/she pass away without fulfilling the Qadhaa Salaats. An easy method to fulfil the Qadhaa Salaats is, after each daily Fardh Salaat, for example, after Dhuhr Salaat of today, perform one Dhuhr Qadhaa Salaat.
and Allah Ta’ala Knows Best
