الانبياۤء — Al-Anbiya' Ayat 25
وَمَآ اَرْسَلْنَا مِنْ قَبْلِكَ مِنْ رَّسُوْلٍ اِلَّا نُوْحِيْٓ اِلَيْهِ اَنَّهٗ لَآ اِلٰهَ اِلَّآ اَنَا۠ فَاعْبُدُوْنِ
Wa mā arsalnā min qablika mir rasūlin illā nūḥī ilaihi annahū lā ilāha illā ana fa‘budūn(i).
"And We sent not before you any messenger except that We revealed to him that, "There is no deity except Me, so worship Me.""
