both muslim personal law and islimic jurisprudence combined called islamic law or muhammaden law
there are some difference between muslim personal law and islimic jurisprudence

muslim personal law is the branch of islamic law in which we study among family matters such as
1- marriage
2- divorce
3- dower
4-khula
5-maintenance
6-will
7-inheritence
8-gift
9-guardian
9-waqf
10-mutawalli

in other hand islamic jurisprudence deals with
1- origin of islamic law
2- quran
3- hadith
4-qiyas
5- ijma
6- ijtihad
7- contract
8-ownership
9- hudd
10- tazir
11- administrative law
and many more topics
this law is the interpretation of all kinds of islamic law
its boundary is very vast comparison family laws

in other words muslim personal law related to family matters and remaining all other matters related with islamin jurisprudence

jurisprudence is the translation of all islamic laws
