The Cow - 2:93
"Remember when We raised Mount Tur over you and took a promise from you: "Hold fast to what I command you and listen."But they said: "We listened and disobeyed". Because of their disbelief, their hearts were deceived by the calf. Say: "If you have believed, how badly your faith is guiding you!"
Our Lord's promise to the Children of Israel:
The Table Spread/5:12
"Allah had taken a promise from the Children of Israel and We sent twelve leaders from among them. Allah said: "I am with you if you observe the prayer, pay the zakat, believe in My messengers and respect them, and lend to Allah a good debt. I will cover your sins and give you gardens in which rivers flow. So whoever of you disbelieves after that has gone astray from the right path."
