Quran 78.34-38
And a full cup. There hear they never vain discourse, nor lying - Requital from thy Lord - a gift in payment - Lord of the heavens and the earth, and (all) that is between them, the Beneficent; with Whom none can converse. On the day when the angels and the Spirit stand arrayed, they speak not, saving him whom the Beneficent alloweth and who speaketh right.
