What should one do if the blessed name of the Beloved Prophet ﷺ is mentioned during the Khutbah?
When the blessed name of Beloved Prophet Muhammad ﷺ is mentioned, then one should recite durud sharif silently, it is fardh to remain silent during the Khutbah.
And Allah ﷻ knows the best
Imam Ahmad Rida Khan رحمة الله تعالى عليه
