The word(s) "mindful" appears 32 time(s) in 31 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And certainly We have made the word to reach them so that they may be mindful.

(22) And they shall cry therein for succour: O our Lord! take us out, we will do good deeds other than those which we used to do. Did We not preserve you alive long enough, so that he who would be mindful in it should mind? And there came to you the warner; therefore taste; because for the unjust, there is no helper.

(23) Then those who recite, being mindful,

(24) (It is) a Book We have revealed to you abounding in good that they may ponder over its verses, and that those endowed with understanding may be mindful.

(25) What! he who is obedient during hours of the night, prostrating himself and standing, takes care of the hereafter and hopes for the mercy of his Lord! Say: Are those who know and those who do not know alike? Only the men of understanding are mindful.

(26) And the blind and the seeing are not alike, nor those who believe and do good and the evil-doer; little is it that you are mindful.

(27) So have We made it easy in your tongue that they may be mindful.

(28) Have you then considered him who takes his low desire for his god, and Allah has made him err having knowledge and has set a seal upon his ear and his heart and put a covering upon his eye. Who can then guide him after Allah? Will you not then be mindful?

(29) And of everything We have created pairs that you may be mindful.

(30) And hell is made to appear on that day. On that day shall man be mindful, and what shall being mindful (then) avail him?
