Verse Quran
2:7 Allah hath set a seal on their hearts and on their hearing, and on their eyes is a veil; great is the penalty they (incur).
17:45 When thou dost recite the Qur'an, We put, between thee and those who believe not in the Hereafter, a veil invisible.
18:57 And who doth more wrong than one who is reminded of the Signs of his Lord, but turns away from them, forgetting the (deeds) which his hands have sent forth? Verily We have set veils over their hearts lest they should understand this, and over their ears, deafness, if thou callest them to guidance, even then will they never accept guidance.
18:101 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear.
19:17 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.
31:19 "And be moderate in thy pace, and lower thy voice; for the harshest of sounds without doubt is the braying of the ass."
33:53 O ye who believe! Enter not the Prophet's houses,- until leave is given you,- for a meal, (and then) not (so early as) to wait for its preparation: but when ye are invited, enter; and when ye have taken your meal, disperse, without seeking familiar talk. Such (behaviour) annoys the Prophet: he is ashamed to dismiss you, but Allah is not ashamed (to tell you) the truth. And when ye ask (his ladies) for anything ye want, ask them from before a screen: that makes for greater purity for your hearts and for theirs. Nor is it right for you that ye should annoy Allah's Messenger, or that ye should marry his widows after him at any time. Truly such a thing is in Allah's sight an enormity.
34:54 And between them and their desires, is placed a barrier, as was done in the past with their partisans: for they were indeed in suspicious (disquieting) doubt.
38:32 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).
41:5 They say: "Our hearts are under veils, (concealed) from that to which thou dost invite us, and in our ears in a deafness, and between us and thee is a screen: so do thou (what thou wilt); for us, we shall do (what we will!)"
42:51 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.
45:23 Then seest thou such a one as takes as his god his own vain desire? Allah has, knowing (him as such), left him astray, and sealed his hearing and his heart (and understanding), and put a cover on his sight. Who, then, will guide him after Allah (has withdrawn Guidance)? Will ye not then receive admonition?
83:15 Verily, from (the Light of) their Lord, that Day, will they be veiled.
