[FONT=wf_segoe-ui_light]Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him) was asked: Is it permissible for a woman of advanced years, such as 70 or 90 years old, to uncover her face before her non-mahram relatives? He replied: Allaah says (interpretation of the meaning):
“And as for women past childbearing who do not expect wedlock, it is no sin on them if they discard their (outer) clothing in such a way as not to show their adornment. But to refrain (i.e. not to discard their outer clothing) is better for them. And Allaah is All‑Hearer, All‑Knower”[al-Noor 24:60].
Women past childbearing are elderly women who are not desired in marriage and who do not put on adornment. There is no sin on them if they uncover their faces before non-mahrams, but for them to observe hijab is better and is more on the safe side, because Allaah says “But to refrain (i.e. not to discard their outer clothing) is better for them” [al-Noor 24:60].
And in some cases seeing them may cause fitnah because of their beautiful appearance even if they are old and not wearing adornment. But if they are wearing adornment, it is not permissible for them to refrain from observing hijab. Adornment includes beautifying the face with kohl (cosmetics) and the like. And Allaah is the source of strength. End quote. Fataawa al-Mar’ah al-Muslimah (1/424). [/FONT]
