17:45
وَإِذَا قَرَأْتَ الْقُرآنَ جَعَلْنَا بَيْنَكَ وَبَيْنَ الَّذِينَ لاَ يُؤْمِنُونَ بِالآخِرَةِ حِجَاباً مَّسْتُوراً
When thou dost recite the Qur'an, We put, between thee and those who believe not in the Hereafter, a veil invisible:
19:16
وَاذْكُرْ فِي الْكِتَابِ مَرْيَمَ إِذِ انتَبَذَتْ مِنْ أَهْلِهَا مَكَاناً شَرْقِيّاً
Relate in the Book (the story of) Mary, when she withdrew from her family to a place in the East.
19:17
فَاتَّخَذَتْ مِن دُونِهِمْ حِجَاباً فَأَرْسَلْنَا إِلَيْهَا رُوحَنَا فَتَمَثَّلَ لَهَا بَشَراً سَوِيّاً
She placed a screen (to screen herself) from them; then We sent her our angel, and he appeared before her as a man in all respects.
38:32
فَقَالَ إِنِّي أَحْبَبْتُ حُبَّ الْخَيْرِ عَن ذِكْرِ رَبِّي حَتَّى تَوَارَتْ بِالْحِجَابِ
And he said, "Truly do I love the love of good, with a view to the glory of my Lord,"- until (the sun) was hidden in the veil (of night):
42:51
وَمَا كَانَ لِبَشَرٍ أَن يُكَلِّمَهُ اللَّهُ إِلَّا وَحْياً أَوْ مِن وَرَاء حِجَابٍ أَوْ يُرْسِلَ رَسُولاً فَيُوحِيَ بِإِذْنِهِ مَا يَشَاءُ إِنَّهُ عَلِيٌّ حَكِيمٌ
It is not fitting for a man that Allah should speak to him except by inspiration, or from behind a veil, or by the sending of a messenger to reveal, with Allah's permission, what Allah wills: for He is Most High, Most Wise.
