The word(s) "thanks" appears 38 time(s) in 34 verse(s) in Quran in Muhammad Pickthal translation.

(11) And what think those who invent a lie concerning Allah (will be their plight) upon the Day of Resurrection? Lo! Allah truly is Bountiful toward mankind, but most of them give not thanks.

(12) And I have followed the religion of my fathers, Abraham and Isaac and Jacob. It never was for us to attribute aught as partner to Allah. This is of the bounty of Allah unto us (the seed of Abraham) and unto mankind; but most men give not thanks.

(13) And when your Lord proclaimed: If ye give thanks, I will give you more; but if ye are thankless, lo! My punishment is dire.

(14) And He it is Who hath constrained the sea to be of service that ye eat fresh meat from thence, and bring forth from thence ornaments which ye wear. And thou seest the ships ploughing it that ye (mankind) may seek of His bounty and that haply ye may give thanks.

(15) And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks.

(16) And the camels! We have appointed them among the ceremonies of Allah. Therein ye have much good. So mention the name of Allah over them when they are drawn up in lines. Then when their flanks fall (dead), eat thereof and feed the beggar and the suppliant. Thus have We made them subject unto you, that haply ye may give thanks.

(17) He it is Who hath created for you ears and eyes and hearts. Small thanks give ye!

(18) One with whom was knowledge of the Scripture said: I will bring it thee before thy gaze returneth unto thee. And when he saw it set in his presence, (Solomon) said: This is of the bounty of my Lord, that He may try me whether I give thanks or am ungrateful. Whosoever giveth thanks he only giveth thanks for (the good of) his own soul; and whosoever is ungrateful (is ungrateful only to his own soul's hurt). For lo! my Lord is Absolute in independence, Bountiful.

(19) Lo! thy Lord is full of bounty for mankind, but most of them do not give thanks.

(20) Ye serve instead of Allah only idols, and ye only invent a lie. Lo! those whom ye serve instead of Allah own no provision for you. So seek your provision from Allah, and serve Him, and give thanks unto Him, (for) unto Him ye will be brought back.
