Obligation for the Imam to perform Sujud-ul-Sahw if the time between concluding the Salah and remembering to perform it is not long

Q 1: What is the ruling if the Imam (the one who leads congregational Prayer) was required to perform Sujud-ul-Sahw (Prostration of Forgetfulness), but he did not remember it until after (Part No. 6; Page No. 40) the Ma’mums (persons being led by an Imam in Prayer) had left the Masjid (mosque)?

A: If the Imam forgets to perform Sujud-ul-Sahw, he should perform it if the time between concluding the Salah (Prayer) and remembering to perform it is short. As for the Ma’mums who leave the Masjid not knowing about it, nothing is required of them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
