The word(s) "care" appears 22 time(s) in 20 verse(s) in Quran in Muhammad Pickthal translation.

(1) Remember Allah through the appointed days. Then whoso hasteneth (his departure) by two days, it is no sin for him, and whoso delayeth, it is no sin for him; that is for him who wardeth off (evil). Be careful of your duty to Allah, and know that unto Him ye will be gathered.

(2) And when it is said unto him: Be careful of thy duty to Allah, pride taketh him to sin. Hell will settle his account, an evil resting-place.

(3) They question thee (O Muhammad) concerning menstruation. Say: It is an illness, so let women alone at such times and go not in unto them till they are cleansed. And when they have purified themselves, then go in unto them as Allah hath enjoined upon you. Truly Allah loveth those who turn unto Him, and loveth those who have a care for cleanness.

(4) O mankind! Be careful of your duty to your Lord Who created you from a single soul and from it created its mate and from them twain hath spread abroad a multitude of men and women. Be careful of your duty toward Allah in Whom ye claim (your rights) of one another, and toward the wombs (that bare you). Lo! Allah hath been a watcher over you.

(5) O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye do.

(6) And this is a blessed Scripture which We have revealed, confirming that which (was revealed) before it, that thou mayst warn the Mother of Villages and those around her. Those who believe in the Hereafter believe herein, and they are careful of their worship.

(7) Such is Allah, your Lord. There is no Allah save Him, the Creator of all things, so worship Him. And He taketh care of all things.

(8) O ye who believe! Be careful of your duty to Allah, and be with the truthful.

(9) Send him with us to-morrow that he may enjoy himself and play. And lo! we shall take good care of him.

(10) And he of Egypt who purchased him said unto his wife: Receive him honourably. Perchance he may prove useful to us or we may adopt him as a son. Thus we established Joseph in the land that We might teach him the interpretation of events. And Allah was predominant in His career, but most of mankind know not.
