سورة Al-Baqarah ( The Cow ) - الآية 93

And recall what time We took your bond and raised over you the Tur, saying: hold fast to that which We have vouchsafed unto you and hearken. They said: we hear and we disobey. And into their hearts the calf was made to sink because of their infidelity. Say thou: vile is that which your belief commandeth you, if ye are believers.
