Does talking during the Adhan using prohibited speech invalidate the Adhan?
Chapter on Adhan
Al-Mughni
Book of Prayer
Primary text
There are two opinions among our companions regarding speech that is inherently forbidden, such as cursing. One view states that it does not invalidate the Adhan because it does not interfere with the primary objective, resembling permissible speech. The second view is that it does invalidate the Adhan because it is a prohibited act within it.
