As-Salāmu `Alaykum (السلام عليكم):
Just so amazed how Muslims have all the technology at their disposal and only use it for worldly concerns.
What happened to recording the lecture? Recorders and video recorders have been invented. How about applying a little effort in figuring out a simple solution. There are countless Muslims who have encountered this concern before at Universities and make the decision that altering or rescheduling one class is done to secure a religious obligation.
The question may not even be the class being scheduled during Jummah. What will be the excuse when you gain employment? The employer refuses to allow you to leave for one hour? Oh forgot about the lunch break.
We can make excuses for everything. A Muslims faith dictates their actions.
You made a good point that you are paying for these classes. Reschedule the class. You are paying the school, the school isn't paying you. Allah has full control. Don't give control to a professor.
I am confidant you will make the correct decision. Insha Allah
The University education is limited to the years you study but your faith lasts a lifetime or doesn't.
