(Al-Ahraf) 7 : 59
لَقَدْ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِ فَقَالَ يَا قَوْمِ اعْبُدُوا اللَّهَ مَا لَكُمْ مِنْ إِلَٰهٍ غَيْرُهُ إِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ عَظِيمٍ
Surely We had sent Noah to his people; then he said: "Oh my people! You serve Lord Allah, you have no Deity besides Him, indeed I fear the punishment of a great Day upon you".
