Sura al-Naml 27:28

ٱذْهَب بِّكِتَٰبِى هَٰذَا فَأَلْقِهْ إِلَيْهِمْ ثُمَّ تَوَلَّ عَنْهُمْ فَٱنظُرْ مَاذَا يَرْجِعُونَ

idhhab bi-kitābī hādhā fa-alqih ilayhim thumma tawalla ʿanhum fa-anẓur mādhā yarjiʿūna

"Go thou, with this letter of mine, and deliver it to them: then draw back from them, and (wait to) see what answer they return"...
