The word(s) "thank" appears 70 time(s) in 62 verse(s) in Quran in Muhammad Pickthal translation.

(51) And the two seas are not alike: this, fresh, sweet, good to drink, this (other) bitter, salt. And from them both ye eat fresh meat and derive the ornament that ye wear. And thou seest the ship cleaving them with its prow that ye may seek of His bounty, and that haply ye may give thanks.

(52) That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks?

(53) Benefits and (divers) drinks have they from them. Will they not then give thanks?

(54) If ye are thankless, yet Allah is Independent of you, though He is not pleased with thanklessness for His bondmen; and if ye are thankful He is pleased therewith for you. No laden soul will bear another's load. Then unto your Lord is your return; and He will tell you what ye used to do. Lo! He knoweth what is in the breasts (of men).

(55) Nay, but Allah must thou serve, and be among the thankful!

(56) Allah it is Who hath appointed for you night that ye may rest therein, and day for seeing. Lo! Allah is a Lord of bounty for mankind, yet most of mankind give not thanks.

(57) Allah it is Who hath made the sea of service unto you that the ships may run thereon by His command, and that ye may seek of His bounty, and that haply ye may be thankful;

(58) And We have commended unto man kindness toward parents. His mother beareth him with reluctance, and bringeth him forth with reluctance, and the bearing of him and the weaning of him is thirty months, till, when he attaineth full strength and reacheth forty years, he saith: My Lord! Arouse me that I may give thanks for the favour wherewith Thou hast favoured me and my parents, and that I may do right acceptable unto Thee. And be gracious unto me in the matter of my seed. Lo! I have turned unto Thee repentant, and lo! I am of those who surrender (unto Thee).

(59) As grace from Us. Thus We reward him who giveth thanks.

(60) If We willed We verily could make it bitter. Why then, give ye not thanks?
