The word(s) "grateful" appears 63 time(s) in 57 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Even then We did forgive you; there was a chance for you to be grateful.

(2) Then We raised you up after your death: Ye had the chance to be grateful.

(3) Then do ye remember Me; I will remember you. Be grateful to Me, and reject not Faith.

(4) O ye who believe! Eat of the good things that We have provided for you, and be grateful to Allah, if it is Him ye worship.

(5) Ramadhan is the (month) in which was sent down the Qur'an, as a guide to mankind, also clear (Signs) for guidance and judgment (Between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting, but if any one is ill, or on a journey, the prescribed period (Should be made up) by days later. Allah intends every facility for you; He does not want to put to difficulties. (He wants you) to complete the prescribed period, and to glorify Him in that He has guided you; and perchance ye shall be grateful.

(6) Didst thou not Turn by vision to those who abandoned their homes, though they were thousands (In number), for fear of death? Allah said to them: "Die": Then He restored them to life. For Allah is full of bounty to mankind, but Most of them are ungrateful.

(7) Allah will deprive usury of all blessing, but will give increase for deeds of charity: For He loveth not creatures ungrateful and wicked.

(8) What can Allah gain by your punishment, if ye are grateful and ye believe? Nay, it is Allah that recogniseth (all good), and knoweth all things.

(9) O ye who believe! when ye prepare for prayer, wash your faces, and your hands (and arms) to the elbows; Rub your heads (with water); and (wash) your feet to the ankles. If ye are in a state of ceremonial impurity, bathe your whole body. But if ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands, Allah doth not wish to place you in a difficulty, but to make you clean, and to complete his favour to you, that ye may be grateful.

(10) Allah will not call you to account for what is futile in your oaths, but He will call you to account for your deliberate oaths: for expiation, feed ten indigent persons, on a scale of the average for the food of your families; or clothe them; or give a slave his freedom. If that is beyond your means, fast for three days. That is the expiation for the oaths ye have sworn. But keep to your oaths. Thus doth Allah make clear to you His signs, that ye may be grateful.
