 Most of the Fatimid mausoleums have either been destroyed or have been greatly altered through later renovations . The Mashad al @-@ Juyushi , also called Mashad Badr al @-@ Jamali , is an exception . This building has a prayer hall covered with cross @-@ vaults , with a dome resting on squinches over the area in front of the mihrab . It has a courtyard with a tall square minaret . It is not clear whom the <unk> commemorates . Two other important <unk> from the Fatimid era in Cairo are those of <unk> <unk> and <unk> al @-@ Shabib , in the Fustat cemetery . <unk> <unk> , a descendant of Ali , never visited Egypt , but the <unk> was built to commemorate her . It is similar to al @-@ Juyushi , but with a larger , fluted dome and with an elegantly decorated mihrab .
