The word(s) "heed" appears 32 time(s) in 32 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) There is no blame on you if ye make an offer of betrothal or hold it in your hearts. Allah knows that ye cherish them in your hearts: But do not make a secret contract with them except in terms Honourable, nor resolve on the tie of marriage till the term prescribed is fulfilled. And know that Allah Knoweth what is in your hearts, and take heed of Him; and know that Allah is Oft-forgiving, Most Forbearing.

(2) Lost are those who slay their children, from folly, without knowledge, and forbid food which Allah hath provided for them, inventing (lies) against Allah. They have indeed gone astray and heeded no guidance.

(3) Many are the Jinns and men we have made for Hell: They have hearts wherewith they understand not, eyes wherewith they see not, and ears wherewith they hear not. They are like cattle,- nay more misguided: for they are heedless (of warning).

(4) And do thou (O reader!) Bring thy Lord to remembrance in thy (very) soul, with humility and in reverence, without loudness in words, in the mornings and evenings; and be not thou of those who are unheedful.

(5) See they not that they are tried every year once or twice? Yet they turn not in repentance, and they take no heed.

(6) Those who rest not their hope on their meeting with Us, but are pleased and satisfied with the life of the present, and those who heed not Our Signs,-

(7) They rejected Him, but We delivered him, and those with him, in the Ark, and We made them inherit (the earth), while We overwhelmed in the flood those who rejected Our Signs. Then see what was the end of those who were warned (but heeded not)!

(8) "This day shall We save thee in the body, that thou mayest be a sign to those who come after thee! but verily, many among mankind are heedless of Our Signs!"

(9) These two kinds (of men) may be compared to the blind and deaf, and those who can see and hear well. Are they equal when compared? Will ye not then take heed?

(10) "And O my people! who would help me against Allah if I drove them away? Will ye not then take heed?
