Q:
I solely performed the first two Rak`ahs (units of prayers) of `Isha' (night) Prayer subvocally, Should I make up for this by offering Sujud-ul-Sahw (Prostration of Forgetfulness) at the end of the Salah (prayer)
or not?
A:
You are not obliged to offer Sujud-ul-Sahw for this, for reciting out loud in the Jahri Salah (Prayer recited out loud) or subvocally in the Sirri Salah (Prayer with subvocal recitation) is an act of Sunnah (supererogatory act of worship following the example of the Prophet). But if you offer Sujud-ul-Sahw, then this is better, for the general Hadiths indicating the prescription for offering Sujud-ul-Sahw for whoever adds or subtracts any action or word (in Salah).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
