if you are a beginner then you can start with LQToronto, they have a nice video course. They are not sunni, however, there is nothing in the course contents related to aqaid except arabic grammar. there are three books in the course (pdfs available online), and I finished only first two books. I realized, after i studied different sarf and nahw books taught in dars e nizami course, that the teacher has over simplified the grammatical analysis of sentences which is fine for beginners, however for a good grasp of arabic texts one needs to have good command over grammatical analysis.
As-salamu 'alaykum I'm looking for nahw and sarf related courses online. Whether they are courses in academies or youtube videos, both kinds will be appreciated. Attending classes physically is not an option. Any recommendations?
