Surat Hud (25-26)

{وَلَقَدْ أَرْسَلْنَا نُوحاً إِلَى قَوْمِهِ إِنِّي لَكُمْ نَذِيرٌ مُّبِينٌ} (هود : 25)

25- Indeed, We sent Noah to his unbelieving people who worshipped idols in Iraq. Noah said to them: I have been sent to you as a Messenger of Allah to warn you in a clear message and speech.

{أَن لاَّ تَعْبُدُواْ إِلاَّ اللّهَ إِنِّيَ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ أَلِيمٍ} (هود : 26)

26- This speech is to worship Allah alone for He is the Only True God who must be worshipped. I fear if you continue in your disbelief and disobedience, you shall be inflicted by a severe torment on the Day of Recompense.
