warning against disbelief

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

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."

قَالَ لَهُۥ صَاحِبُهُۥ وَهُوَ يُحَاوِرُهُۥٓ أَكَفَرْتَ بِٱلَّذِى خَلَقَكَ مِن تُرَابٍ ثُمَّ مِن نُّطْفَةٍ ثُمَّ سَوَّىٰكَ رَجُلًا

وَأَنذِرْ عَشِيرَتَكَ ٱلْأَقْرَبِينَ

And warn, [O Muḥammad], your closest kindred.

يَوْمَ نَقُولُ لِجَهَنَّمَ هَلِ ٱمْتَلَأْتِ وَتَقُولُ هَلْ مِن مَّزِيدٍ

On the Day We will say to Hell, "Have you been filled?" and it will say, "Are there some more,"

فَوَيْلٌ يَوْمَئِذٍ لِّلْمُكَذِّبِينَ

Then woe, that Day, to the deniers,
