Quran 7:59 Al-A'raf, ayah 59 of 206

لَقَدْ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِۦ فَقَالَ يَـٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَـٰهٍ غَيْرُهُۥٓ إِنِّىٓ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ عَظِيمٍ ۝٥٩

7:59 We sent Noah (of old) unto his people, and he said: O my people! Serve Allah. Ye have no other Allah save Him. Lo! I fear for you the retribution of an Awful Day.
