قُلْتُ الْمُحْرِمُ يُؤْذِيهِ الذُّبَابُ حِينَ يُرِيدُ النَّوْمَ يُغَطِّي وَجْهَهُ قَالَ نَعَمْ وَ لَا يُخَمِّرْ رَأْسَهُ وَ الْمَرْأَةُ عِنْدَ النَّوْمِ لَا بَأْسَ بِأَنْ تُغَطِّيَ وَجْهَهَا كُلَّهُ عِنْدَ النَّوْمِ[1].
“I once asked abu Ja’far (a.s.), about a man who covers his face when sleeping because of flies that bother him. He (the Imam) said, ’Yes, he can do so, but must not cover his head; and women are permitted to cover their faces when they sleep.”’
