What should you do if you make a mistake during the prayer or if you are not certain of how many rak`ahs you have performed? Should you repeat the prayer or should you make up the missed part by performing sujud al-sahw (two prostrations of forgetfulness)? Should sujud al-sahw be done before or after ending the prayer?
Watch this final episode of the Prophet’s prayer by Dr. Muhammad Salah to know the answer to these questions.
