Q 1: While leading the `Asr (Afternoon) Prayer, the Imam (the one who leads congregational Prayer) remembered, when he was sitting during the second Rak`ah (unit of Prayer), that he had not performed the Zhuhr (Noon) Prayer. He said the Taslim (salutation of peace ending the Prayer) and told the congregation that he had not offered the Zhuhr Prayer and so it was not permissible for him to lead them in the `Asr Prayer. What is the ruling on those who were led by him? What is the ruling on the Imam? Is their Salah (Prayer) valid or not?

(Part No. 7; Page No. 398)  A: Anyone who remembers a missing Salah while they are offering another obligatory one should complete the Salah that they are offering. This Salah will be supererogatory for them and an obligatory one for those they are leading. They should then make up for the missed Salah, and perform the due one that they performed previously, as it was only a supererogatory one then. However, as the Imam interrupted the Salah, he should perform the Salah that he forgot, and then the one he interrupted. As for the Ma'mums (those being led by the Imam in Prayer), whose Salah the Imam interrupted, it is permissible for them to complete their Salah with another Imam, chosen from among them, in place of the first one. But if they performed their Salah individually, this was permissible, because they had an excuse for doing so and they had not done anything that nullified their Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
