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

When Allah took a compact concerning the prophets, [He said,] ‘Inasmuch as I have given you [the knowledge] of the Book and wisdom, should an apostle come to you thereafter confirming what is with you, you shall believe in him and help him.’ He said, ‘Do you pledge and accept My covenant on this condition?’ They said, ‘We pledge.’ He said, ‘Then be witnesses, and I, too, am among the witnesses along with you.’
