Assalamu Alaikum wa Rahmatullahi wa Barakatuh , How to combine the lessons of SOK and how to learn Arabic language to have comprehensive study, i don't know where I can learn online Arabic so it could give me the comprehensive benefit, if you could give me advice, i am completely beginner ....

I am doing my best to present to you what you would get if u actually knew Arabic as well as making it foundational, research based, and concise, so focus on learning the knowledge itself; this is top priority. As for Arabic, there are specialists just for that, and they know better than I, may Allah reward us and you.
