Quran Chapter 2 Verse 74-76
Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allah . And Allah is not unaware of what you do.
Do you covet [the hope, O believers], that they would believe for you while a party of them used to hear the words of Allah and then distort the Torah after they had understood it while they were knowing?
And when they meet those who believe, they say, “We have believed”; but when they are alone with one another, they say, “Do you talk to them about what Allah has revealed to you so they can argue with you about it before your Lord?” Then will you not reason?
