Assalamu Alaikum, Check this link http://www.sunniforum.com/forum/show...audio-lectures It has sources to other darse nizami books. Fiqh, usool fiqh, grammar, balagha and much more. I'm using them and the teacher is very good ma'sha Allah. For fiqh, use his Quduri links, in'sha Allah it will help a lot. But if you can go through his Hidayatun Nahw first (which is grammar), it will save you much time in reading more advanced books.
