The word(s) "heed" appears 26 time(s) in 26 verse(s) in Quran in Mohsin Khan translation.

(1) And this is the Path of your Lord (the Qur'an and Islam) leading Straight. We have detailed Our Revelations for a people who take heed.

(2) And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain). Till when they have carried a heavy-laden cloud, We drive it to a land that is dead, then We cause water (rain) to descend thereon. Then We produce every kind of fruit therewith. Similarly, We shall raise up the dead, so that you may remember or take heed.

(3) And indeed We punished the people of Fir'aun (Pharaoh) with years of drought and shortness of fruits (crops), that they might remember (take heed).

(4) So We took retribution from them. We drowned them in the sea, because they belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and were heedless about them.

(5) I shall turn away from My Ayat (verses of the Qur'an) those who behave arrogantly on the earth, without a right, and (even) if they see all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will not believe in them. And if they see the way of righteousness (monotheism, piety, and good deeds), they will not adopt it as the Way, but if they see the way of error (polytheism, crimes and evil deeds), they will adopt that way, that is because they have rejected Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and were heedless (to learn a lesson) from them.

(6) And surely, We have created many of the jinn and mankind for Hell. They have hearts wherewith they understand not, and they have eyes wherewith they see not, and they have ears wherewith they hear not (the truth). They are like cattle, nay even more astray; those! They are the heedless ones.

(7) Verily, those who hope not for their meeting with Us, but are pleased and satisfied with the life of the present world, and those who are heedless of Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.),

(8) So this day We shall deliver your (dead) body (out from the sea) that you may be a sign to those who come after you! And verily, many among mankind are heedless of Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(9) It is not for any person to believe, except by the Leave of Allah, and He will put the wrath on those who are heedless.

(10) The likeness of the two parties is as the blind and the deaf and the seer and the hearer. Are they equal when compared? Will you not then take heed?
