Ṣadr-ush-Sharī’aĥ, Badr-uṭ-Ṭarīqaĥ, ‘Allāmaĥ Maulānā Muftī Muhammad Amjad ‘Alī A’ẓamī عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی says: A man is also allowed to touch the parts of a Maḥram woman’s body that he is permitted to look at, as long as there is no risk of lust for both. A man may massage his mother’s feet, however, he can only massage her thigh if it is covered by a cloth, touching her thigh directly whilst it is uncovered is prohibited. (Baĥār-e-Sharī’at, part 16, pp. 88)
Question: Is a man allowed to look at a non-Maḥram woman’s face?
Answer: He should not. However, if necessary he can, but with certain conditions. Explaining some situations for this, Ṣadr-ush-Sharī’aĥ, Badr-uṭ-Ṭarīqaĥ, ‘Allāmaĥ Maulānā Muftī Muhammad Amjad ‘Alī A’ẓamī عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی says: The rule for looking at a non-Maḥram woman is that (if necessary) he may look at her face and palms because sometimes this is necessary. For example, if a witness who is to testify for or against her in a court-case is prevented from looking at her, then how can he testify for or against her? However, even here, there must be no possibility of lust whilst looking at her. These days, this is needed because (in markets, on public streets) many women walk around outside their homes, and to avoid seeing their faces at all is very difficult. Some scholars permit looking at their feet as well. (Ibid, pp. 89)
He رَحْمَةُ الـلّٰـهِ تَـعَـالٰی عَـلَيْـه further states: Although it is permissible to look at the face of a non-Maḥram woman without any chance of lust, these are irreligious times. People of this era are not like the earlier generations, hence, in this era, looking at it (face) will be prevented, however it is permissible for a witness or judge to look in case of necessity. (Ibid, pp. 89, 90)
