The respective subject is quite an easy and understandable one,anyone who has not remained the student of law,even he can get it easily.

The recommended books are:
for Muslim Law: by D.F Mullah and

for Muslim Jurisprudence: by Abdur Rahim are complete books for proper preparation.

if you want to study more,let me know, i will then suggest you few other.
good luck.
