Surah Al-A'raf — Ayah 59 (7:59)
لَقَدۡ أَرۡسَلۡنَا نُوحًا إِلَىٰ قَوۡمِهِۦ فَقَالَ يَٰقَوۡمِ ٱعۡبُدُواْ ٱللَّهَ مَا لَكُم مِّنۡ إِلَٰهٍ غَيۡرُهُۥٓ إِنِّيٓ أَخَافُ عَلَيۡكُمۡ عَذَابَ يَوۡمٍ عَظِيمٖ ٥٩
English translation (Saheeh International)
We had certainly sent Noah to his people, and he said, "O my people, worship Allāh; you have no deity other than Him. Indeed, I fear for you the punishment of a tremendous Day."
Brief commentary
Indeed I sent Noah as a messenger to his people calling them to the Oneness of Allah and to leave off worshipping anything besides Him. Noah said to them: 'O people! Worship Allah alone, you have no true God except Him. I fear for you O people, the punishment of a great day if you persist in your disbelief.'
