The word(s) "ink" appears 160 time(s) in 152 verse(s) in Quran in Mohsin Khan translation.

(81) Do people think that they will be left alone because they say: "We believe," and will not be tested.

(82) Or think those who do evil deeds that they can outstrip Us (i.e. escape Our punishment)? Evil is that which they judge!

(83) Do they not think deeply (in their ownselves) about themselves (how Allah created them from nothing, and similarly He will resurrect them)? Allah has created not the heavens and the earth, and all that is between them, except with truth and for an appointed term. And indeed many of mankind deny the Meeting with their Lord. [Tafsir At-Tabari].

(84) And if all the trees on the earth were pens and the sea (were ink wherewith to write), with seven seas behind it to add to its (supply), yet the Words of Allah would not be exhausted. Verily, Allah is All-Mighty, All-Wise.

(85) They think that Al-Ahzab (the Confederates) have not yet withdrawn; and if Al-Ahzab (the Confederates) should come (again), they would wish they were in the deserts (wandering) among the bedouins, seeking news about you (from a far place); and if they (happen) to be among you, they would not fight but little.

(86) See they not what is before them and what is behind them, of the heaven and the earth? If We will, We shall sink the earth with them, or cause a piece of the heaven to fall upon them. Verily, in this is a sign for every slave who turns to Allah in repentance (i.e. the one who believes in the Oneness of Allah and performs deeds of His obedience and always begs His Pardon).

(87) And the two seas (kinds of water) are not alike: this is palatable, sweet and pleasant to drink, and that is salt and bitter. And from them both you eat fresh tender meat (fish), and derive the ornaments that you wear. And you see the ships cleaving (the sea-water as they sail through it), that you may seek of His Bounty, and that you may give thanks.

(88) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? Nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(89) And they have (other) benefits from them, and they get (milk) to drink. Will they not then be grateful?

(90) White, delicious to the drinkers.
