Chapter 160 | Lawful Instances of Looking at Women
2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مَرْوَكِ بْنِ عُبَيْدٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اللهِ قَالَ قُلْتُ لَهُ مَا يَحِلُّ لِلرَّجُلِ أَنْ يَرَى مِنَ الْمَرْأَةِ إِذَا لَمْ يَكُنْ مَحْرَماً قَالَ الْوَجْهُ وَالْكَفَّانِ وَالْقَدَمَانِ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Marwak ibn ‘Ubayd from certain persons of our people who has said the following: “I once asked abu ’Abd Allah , about how much of the body of a woman who is not of one’s relatives one can look at. He (the Imam) said, ‘It is her face, both hands (from wrist down) and both feet (from the ankles down).”’
