Should the Ma'mum (a person being led by an Imam in Prayer) perform Sujud-ul-Sahw (Prostration of Forgetfulness), if they forget to do any of the obligatory acts?
It is not obligatory for the Ma'mum to perform Sujud-ul-Sahw for neglecting an obligatory action. This is not legislated for them, unless they miss a Rak`ah (unit of Prayer) or more with the Imam (the one who leads congregational Prayer), in which case they should perform Sujud-ul-Sahw for what they had forgot while following the Imam or while making up for what they had missed with the Imam. They should make up for the missed Rak`ahs first, then perform Sujud-ul-Sahw.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
