The word(s) "covering" appears 18 time(s) in 17 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Allah has set a seal upon their hearts and upon their hearing and there is a covering over their eyes, and there is a great punishment for them.

(2) They shall have a bed of hell-fire and from above them coverings (of it); and thus do We reward the unjust.

(3) And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil).

(4) Now surely they fold up their breasts that they may conceal (their enmity) from Him; now surely, when they use their garments as a covering, He knows what they conceal and what they make public; surely He knows what is in the breasts.

(5) Their shirts made of pitch and the fire covering their faces

(6) And We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.

(7) And say to the believing women that they cast down their looks and guard their private parts and do not display their ornaments except what appears thereof, and let them wear their head-coverings over their bosoms, and not display their ornaments except to their husbands or their fathers, or the fathers of their husbands, or their sons, or the sons of their husbands, or their brothers, or their brothers' sons, or their sisters' sons, or their women, or those whom their right hands possess, or the male servants not having need (of women), or the children who have not attained knowledge of what is hidden of women; and let them not strike their feet so that what they hide of their ornaments may be known; and turn to Allah all of you, O believers! so that you may be successful.

(8) And He it is Who made the night a covering for you, and the sleep a rest, and He made the day to rise up again.

(9) But they called him a liar, so the punishment of the day of covering overtook them; surely it was the punishment of a grievous day.

(10) They shall have coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants!
