سورة Al-Imran ( The Famiy of Imran ) - الآية 81

And recall when Allah took a covenant from the Prophets: 'This is the Book and the Wisdom which I have given you. But should a Prophet come to you confirming that which is already with you, you shall believe in him and shall help him. So saying, Allah asked: 'Do you agree and accept to take up the burden of the covenant?' They answered: 'We agree,' He said: 'Then bear wirness; and I will be with you among the witness.
