The word(s) "fingertip" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) Here you are loving them but they are not loving you, while you believe in the Scripture - all of it. And when they meet you, they say, "We believe." But when they are alone, they bite their fingertips at you in rage. Say, "Die in your rage. Indeed, Allah is Knowing of that within the breasts."

(2) [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip."

(3) Yes. [We are] Able [even] to proportion his fingertips.
