Question
I was praying the Sunnah prayer in the mosque after the obligatory Dhuhr prayer, when one of the brothers came and made me an imam for him to pray the Dhuhr prayer in congregation. I know that the following of the obligatory by the supererogatory is not permissible in our Hanafi school of thought. What should I do in this case?
Answer
I say, and with God's success: In the Hanafi school, it is not valid, but in the Shafi'i school, it is valid according to what is known, so you can overlook this and continue your prayer, and his prayer according to the opinion of others is valid, and God knows best.
