Changing a Kafir's name

A: It is not Wajib to change the names of the new convert to Islam unless these names are unacceptable by Islamic law such as: `Abd Yaghuth, `Abdul Hussayn, `Abdul `Uza, or `Abd Manat. Such names should be changed to Islamic names; however, it is not obligatory to change the names of their fathers or their grandfathers.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
