"...it is not permissible to marry her [an atheist], as she is still a Kafir (non-Muslim) and has not yet embraced Islam wholeheartedly without any doubt. Allah says: "And do not marry Al-Mushrikât (idolatresses, etc.) till they believe (worship Allâh Alone). And indeed a slave woman who believes is better than a (free) Mushrikah (idolatress, etc.), even though she pleases you."(Al-Baqarah 2:221). Being convinced by Islam and wishing to embrace it is not an excuse for you to get married with her..." - Dr. Abdullah Al-faqih
