There is a teacher called Asif Meher Ali who teaches Arabic using Madinah Books 1, 2, and 3 completely free in YouTube channel. Should I learn from him, or should I be cautious about my ‘aqeedah—since in one video he had a beard and in another he was clean-shaven?

I do not know him whatsoever. So, i cant answer this questiom, but I will give a general rule for everything in serling knowledge. Always take from a trusted source or don't take.
