The word(s) "care" appears 86 time(s) in 80 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) Whatever Allah has restored to His Apostle from the people of the towns, it is for Allah and for the Apostle, and for the near of kin and the orphans and the needy and the wayfarer, so that it may not be a thing taken by turns among the rich of you, and whatever the Apostle gives you, accept it, and from whatever he forbids you, keep back, and be careful of (your duty to) Allah; surely Allah is severe in retributing (evil):

(72) O you who believe! be careful of (your duty to) Allah, and let every soul consider what it has sent on for the morrow, and be careful of (your duty to) Allah; surely Allah is Aware of what you do.

(73) And if anything (out of the dowries) of your wives has passed away from you to the unbelievers, then your turn comes, give to those whose wives have gone away the like of what they have spent, and be careful of (your duty to) Allah in Whom you believe.

You do not know that Allah may after that bring about reunion.

(76) So when they have reached their prescribed time, then retain them with kindness or separate them with kindness, and call to witness two men of justice from among you, and give upright testimony for Allah. With that is admonished he who believes in Allah and the latter day; and whoever is careful of (his duty to) Allah, He will make for him an outlet,

(77) And (as for) those of your women who have despaired of menstruation, if you have a doubt, their prescribed time shall be three months, and of those too who have not had their courses; and (as for) the pregnant women, their prescribed time is that they lay down their burden; and whoever is careful of (his duty to) Allah He will make easy for him his affair.

(78) That is the command of Allah which He has revealed to you, and whoever is careful of (his duty to) Allah, He will remove from him his evil and give him a big reward.

(79) Allah has prepared for them severe chastisement, therefore be careful of (your duty to) Allah, O men of understanding who believe! Allah has indeed revealed to you a reminder,

(80) That you should serve Allah and be careful of (your duty to) Him and obey me:
