Muslim Law isn't that technical subject. However if you are finding problems you may consult the book by Asif Malik, Emporium Publisher's book, it gives all topics as well as objective covered in this book is quite handy. You may also consult Liaqat Niazi book, its good though he didn't discuss few important topics in required details....
On the other hand there can be no denying that D F Mulla's book is authority in this regard....
Regards
