quran:7:59 –

We had certainly sent Noah to his people, and he said, "O my people, worship Allah; you have no deity other than Him. Indeed, I fear for you the punishment of a tremendous Day.  

Verily (laqad is the response to an oath that has been omitted) We sent Noah to his people, and he said, ‘O my people, worship God! You have no god other than Him (read ghayrihi as an adjective of ilāh, ‘god’, or ghayruhu as a substitution in its place ˹sc. instead of min ilāhin, ‘any god’). Truly, I fear for you, if you worship other than Him, the chastisement of an Awful Day’, that is, the Day of Resurrection.
القرآن:٧:٥٩ –

لَقَدْ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِ فَقَالَ يَا قَوْمِ اعْبُدُوا اللَّهَ مَا لَكُمْ مِنْ إِلَٰهٍ غَيْرُهُ إِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ عَظِيمٍ  

{لقد} جواب قسم محذوف {أرسلنا نوحا إلى قومه فقال يا قوم اعبدوا الله ما لكم من إله غَيْرُِهُ} بالجر صفة لإله والرفع بدل من محله {إني أخاف عليكم} إن عبدتم غيره {عذاب يوم عظيم} هو يوم القيامة.

quran:23:23 –

And We had certainly sent Noah to his people, and he said, "O my people, worship Allah; you have no deity other than Him; then will you not fear Him?"  

And verily We sent Noah to his people, and he said, ‘O my people, worship God, obey God and affirm His Oneness. You have no ˹other˺ god besides Him (ghayruhu is the subject of mā, ‘no’; the preceding ˹min ilāhin, ‘god’˺ is the predicate, the min being extra). Will you not then fear?’ His punishment in worshipping ˹gods˺ other than Him?
القرآن:٢٣:٢٣ –

وَلَقَدْ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِ فَقَالَ يَا قَوْمِ اعْبُدُوا اللَّهَ مَا لَكُمْ مِنْ إِلَٰهٍ غَيْرُهُ ۖ أَفَلَا تَتَّقُونَ  

{ولقد أرسلنا نوحاً إلى قومه فقال يا قوم اعبدوا الله} أطيعوا الله ووحدوه {مالكم من إله غيره} وهو اسم ما، وما قبله الخبر، ومن زائدة {أفلا تتقون} تخافون عقوبته بعبادتكم غيره.
