Ruling about looking at (non-Mahram) woman

Answering a question regarding looking or not looking at the face of a non-Mahram woman, Shaykh-e-Tareeqat Ameer-e-Ahl-e-Sunnat Maulana Abu Bilal Muhammad Ilyas Attar Qaadiri Razavi دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـهْ has stated: ‘Questions and Answers about Islamic Veil’, publication of Maktaba-tul-Madinah, publication of Dawat-e-Islami: He should not look at the face of a non-Mahram woman. However, if necessary he can, but with certain conditions. Explaining some situations for this, Sadr-us-Shari’ah, Badr-ut-Tareeqah, ‘Allamah Maulana Mufti Muhammad Amjad ‘Ali A’zami رَحْمَةُ اللهِ تَعَالٰی عَلَيْه says: The rule for looking at a non-Mahram 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. (Questions & Answers about Islamic Veil pp. 21)

He رَحْمَةُ الـلّٰـهِ تَـعَـالٰی عَـلَيْـه further states: Although it is permissible to look at the face of a non-Mahram 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.

Remember! It is necessary for a Muslim to know who are those women from whom Islam has commanded to do Purdah and who are those from whom Islam allows not to do Purdah. So, let’s listen about it:

Purdah for men from whom?
