The Cow - 2:63 "We once took a promise from you when We raised Mount Sinai over you, saying: "Hold fast to what We have given you and remember what is in it, that you may be protected"."
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."
