The word(s) "cover" appears 59 time(s) in 53 verse(s) in Quran in Mohsin Khan translation.

(31) And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) and not to show off their adornment except only that which is apparent (like both eyes for necessity to see the way, or outer palms of hands or one eye or dress like veil, gloves, head-cover, apron, etc.), and to draw their veils all over Juyubihinna (i.e. their bodies, faces, necks and bosoms) and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers or their brother's sons, or their sister's sons, or their (Muslim) women (i.e. their sisters in Islam), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of feminine sex. And let them not stamp their feet so as to reveal what they hide of their adornment. And all of you beg Allah to forgive you all, O believers, that you may be successful.

(32) And it is He Who makes the night a covering for you, and the sleep (as) a repose, and makes the day Nushur (i.e. getting up and going about here and there for daily work, after one's sleep at night, or like resurrection after one's death).

(33) It was said to her: "Enter As-Sarh" (a glass surface with water underneath it or a palace): but when she saw it, she thought it was a pool, and she (tucked up her clothes) uncovering her legs. (Sulaiman (Solomon)) said: "Verily, it is a Sarh (a glass surface with water underneath it or a palace)." She said: "My Lord! Verily, I have wronged myself, and I submit [in Islam, together with Sulaiman (Solomon)] to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)."

(34) On the Day when the torment (Hell-fire) shall cover them from above them and from underneath their feet, and it will be said: "Taste what you used to do."

(35) And when a wave covers them like shades (i.e. like clouds or the mountains of sea-water), they invoke Allah, making their invocations for Him only. But when He brings them safe to land, there are among them those that stop in between (Belief and disbelief). But none denies Our Signs except every perfidious ingrate.

(36) And We have put a barrier before them, and a barrier behind them, and We have covered them up, so that they cannot see.

(37) They shall have coverings of Fire, above them and covering (of Fire) beneath them. With this Allah does frighten His slaves: "O My slaves, therefore fear Me!"

(38) Then their Faith (in Islamic Monotheism) could not avail them when they saw Our punishment. (Like) this has been the way of Allah in dealing with His slaves. And there the disbelievers lost utterly (when Our Torment covered them).

(39) And they say: "Our hearts are under coverings (screened) from that to which you invite us; and in our ears is deafness, and between us and you is a screen: so work you (on your way); verily, we are working (on our way)."

(40) covering the people: this is a painful torment.
