The word(s) "dense" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And (as for) those who believe and do good deeds, We will make them enter gardens beneath which rivers flow, to abide in them for ever; they shall have therein pure mates, and We shall make them enter a dense shade.

(2) And (as for) those who have earned evil, the punishment of an evil is the like of it, and abasement shall come upon them-- they shall have none to protect them from Allah-- as if their faces had been covered with slices of the dense darkness of night; these are the inmates of the fire; in it they shall abide.

(3) And gardens dense and luxuriant.
