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

(21) Then see what was the end of those who were warned (but heeded not).

(22) And warn them (O Muhammad صلى الله عليه وسلم) of the Day that is drawing near (i.e. the Day of Resurrection), when the hearts will be choking the throats, and they can neither return them (hearts) to their chests nor can they throw them out. There will be no friend, nor an intercessor for the Zalimun (polytheists and wrong-doers), who could be given heed to.

(23) (It will be said to the sinners): "Indeed you were heedless of this. Now We have removed from you your covering, and sharp is your sight this Day!"

(24) Verily, therein is indeed a reminder for him who has a heart or gives ear while he is heedful.

(25) Who are under a cover of heedlessness (think not about the gravity of the Hereafter),

(26) And indeed, you have already known the first form of creation (i.e. the creation of Adam): why then do you not remember (or take heed)?
