The word(s) "ingrate" appears 9 time(s) in 9 verse(s) in Quran in Mohsin Khan translation.

(1) And He gave you of all that you asked for, and if you count the Blessings of Allah, never will you be able to count them. Verily, man is indeed an extreme wrong-doer, a disbeliever (an extreme ingrate who denies Allah's Blessings by disbelief, and by worshipping others besides Allah, and by disobeying Allah and His Prophet Muhammad صلى الله عليه و سلم).

(2) Truly, Allah defends those who believe. Verily, Allah likes not any treacherous ingrate to Allah [those who disobey Allah but obey Shaitan (Satan)].

(3) It is He, Who gave you life, and then will cause you to die, and will again give you life (on the Day of Resurrection). Verily man is indeed an ingrate.

(4) "And you did your deed, which you did (i.e. the crime of killing a man) while you were one of the ingrates."

(5) So that they become ingrate for that which We have given them, and that they take their enjoyment (as a warning and a threat), but they will come to know.

(6) Have they not seen that We have made (Makkah) a secure sanctuary, while men are being snatched away from all around them? Then do they believe in Batil (falsehood - polytheism, idols and all deities other than Allah), and deny (become ingrate for) the Graces of Allah?

(7) And when a wave covers them like shades (i.e. like clouds or the mountains of sea-water), they invoke Allah, making their invocations for Him only. But when He brings them safe to land, there are among them those that stop in between (Belief and disbelief). But none denies Our Signs except every perfidious ingrate.

(8) But if they turn away (O Muhammad صلى الله عليه و سلم from the Islamic Monotheism, which you have brought to them). We have not sent you (O Muhammad صلى الله عليه و سلم) as a Hafiz (watcher, protector) over them (i.e. to take care of their deeds and to recompense them). Your duty is to convey (the Message). And verily, when We cause man to taste of Mercy from Us, he rejoices thereat; but when some ill befalls them because of the deeds which their hands have sent forth, then verily, man (becomes) ingrate!

(9) Yet, they assign to some of His slaves a share with Him (by pretending that He has children, and considering them as equals or co-partners in worship with Him). Verily, man is indeed a manifest ingrate!
