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

(1) And do not marry the idolatresses until they believe, and certainly a believing maid is better than an idolatress woman, even though she should please you; and do not give (believing women) in marriage to idolaters until they believe, and certainly a believing servant is better than an idolater, even though he should please you; these invite to the fire, and Allah invites to the garden and to forgiveness by His will, and makes clear His communications to men, that they may be mindful.

(2) And do not approach the property of the orphan except in the best manner until he attains his maturity, and give full measure and weight with justice-- We do not impose on any soul a duty except to the extent of its ability; and when you speak, then be just though it be (against) a relative, and fulfill Allah's covenant; this He has enjoined you with that you may be mindful;

(3) O children of Adam! We have indeed sent down to you clothing to cover your shame, and (clothing) for beauty and clothing that guards (against evil), that is the best. This is of the communications of Allah that they may be mindful.

(4) And He it is Who sends forth the winds bearing good news before His mercy, until, when they bring up a laden cloud, We drive it to a dead land, then We send down water on it, then bring forth with it of fruits of all kinds; thus shall We bring forth the dead that you may be mindful.

(5) And certainly We overtook Firon's people with droughts and diminution of fruits that they may be mindful.

(6) And when We shook the mountain over them as if it were a covering overhead, and they thought that it was going to fall down upon them: Take hold of what We have given you with firmness, and be mindful of what is in it, so that you may guard (against evil).

(7) Surely those who guard (against evil), when a visitation from the Shaitan afflicts them they become mindful, then lo! they see.

(8) Therefore if you overtake them in fighting, then scatter by (making an example of) them those who are in their rear, that they may be mindful.

(9) And keep up prayer in the two parts of the day and in the first hours of the night; surely good deeds take away evil deeds this is a reminder to the mindful.

(10) Yielding its fruit in every season by the permission of its Lord? And Allah sets forth parables for men that they may be mindful.
