Taking care of an absent relative's family without having Khulwah with his wife

A: What you are doing with the family of your absent relative is noble and you shall be rewarded. Taking care of the weak by fulfilling their needs is a righteous deed, but it is not permissible for you to sit privately with a female that is a marriageable woman. (Part No. 17; Page No. 62) It is not permissible for her to uncover her face in your presence because you are not one of her Mahrams. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
