1- Is it permissible to deliver lessons before the Friday sermon?

Delivering lessons to teach people and instruct them in matters of their religion is praiseworthy and permissible at any time, as long as it does not disturb the worshippers. However, singling out a lesson before the Friday sermon, believing it to have a special virtue at this time, is not appropriate; because the Prophet, may Allah’s prayers and peace be upon him, nor his companions, nor the righteous predecessors did it. And singling out an act of worship for a specific time requires permission from the Lawgiver.
