The word(s) "thanks" appears 51 time(s) in 48 verse(s) in Quran in Mohsin Khan translation.

(21) "Verily, your Lord is full of Grace for mankind, yet most of them do not give thanks."

(22) And say [(O Muhammad صلى الله عليه وسلم) to these polytheists and pagans.]: "All the praises and thanks be to Allah. He will show you His Ayat (signs, in yourselves, and in the universe or punishments), and you shall recognise them. And your Lord is not unaware of what you do."

(23) And He is Allah: La ilaha illa Huwa (none has the right to be worshipped but He), all praises and thanks be to Him (both) in the first (i.e. in this world) and in the last (i.e. in the Hereafter). And for Him is the Decision, and to Him shall you (all) be returned.

(24) And if you were to ask them: "Who sends down water (rain) from the sky, and gives life therewith to the earth after its death?" they will surely reply: "Allah." Say: "All the praises and thanks be to Allah!" Nay, most of them have no sense.

(25) And His are all the praises and thanks in the heavens and the earth; and (glorify Him) in the afternoon (i.e. offer 'Asr prayer) and when you come up to the time, when the day begins to decline (i.e. offer Zuhr prayer). (Ibn 'Abbas said: "These are the five compulsory congregational prayers mentioned in the Qur'an)." [Tafsir At-Tabari]

(26) And indeed We bestowed upon Luqman Al-Hikmah (wisdom and religious understanding) saying: "Give thanks to Allah." And whoever gives thanks, he gives thanks for (the good of) his ownself. And whoever is unthankful, then verily, Allah is All-Rich (Free of all needs), Worthy of all praise.

(27) And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years - give thanks to Me and to your parents. Unto Me is the final destination.

(28) And if you (O Muhammad صلى الله عليه وسلم) ask them: "Who has created the heavens and the earth," they will certainly say: "Allah." Say: "All the praises and thanks be to Allah!" But most of them know not.

(29) Then He fashioned him in due proportion, and breathed into him the soul (created by Allah for that person); and He gave you hearing (ears), sight (eyes) and hearts. Little is the thanks you give!

(30) And remember (O you the members of the Prophet's family, the Graces of your Lord), that which is recited in your houses of the Verses of Allah and Al-Hikmah (i.e. Prophet's Sunnah - legal ways, so give your thanks to Allah and glorify His Praises for this Qur'an and the Sunnah ). Verily, Allah is Ever Most Courteous, Well-Acquainted with all things.
