قُلْ فَلِلَّهِ ٱلْحُجَّةُ ٱلْبَـٰلِغَةُ ۖ فَلَوْ شَآءَ لَهَدَىٰكُمْ أَجْمَعِينَ

Say, "With Allāh is the far-reaching [i.e., conclusive] argument. If He had willed, He would have guided you all."

Al-An'am 149

قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًا ۗ سُبْحَـٰنَهُۥ ۖ هُوَ ٱلْغَنِىُّ ۖ لَهُۥ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ ۚ إِنْ عِندَكُم مِّن سُلْطَـٰنٍۭ بِهَـٰذَآ ۚ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ

They1 have said, "Allāh has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority2 for this [claim]. Do you say about Allāh that which you do not know?

Yunus 68

قَالَ يَـٰقَوْمِ أَرَءَيْتُمْ إِن كُنتُ عَلَىٰ بَيِّنَةٍ مِّن رَّبِّى وَءَاتَىٰنِى مِنْهُ رَحْمَةً فَمَن يَنصُرُنِى مِنَ ٱللَّهِ إِنْ عَصَيْتُهُۥ ۖ فَمَا تَزِيدُونَنِى غَيْرَ تَخْسِيرٍ

He said, "O my people, have you considered: if I should be upon clear evidence from my Lord and He has given me mercy from Himself, who would protect me from Allāh if I disobeyed Him? So you would not increase me except in loss.

Hud 63

مَا تَعْبُدُونَ مِن دُونِهِۦٓ إِلَّآ أَسْمَآءً سَمَّيْتُمُوهَآ أَنتُمْ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلْطَـٰنٍ ۚ إِنِ ٱلْحُكْمُ إِلَّا لِلَّهِ ۚ أَمَرَ أَلَّا تَعْبُدُوٓا۟ إِلَّآ إِيَّاهُ ۚ ذَٰلِكَ ٱلدِّينُ ٱلْقَيِّمُ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ

You worship not besides Him except [mere] names you have named them,1 you and your fathers, for which Allāh has sent down no evidence. Legislation is not but for Allāh. He has commanded that you worship not except Him. That is the correct religion, but most of the people do not know.

Yusuf 40

۞ قَالَتْ رُسُلُهُمْ أَفِى ٱللَّهِ شَكٌّ فَاطِرِ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ يَدْعُوكُمْ لِيَغْفِرَ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرَكُمْ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۚ قَالُوٓا۟ إِنْ أَنتُمْ إِلَّا بَشَرٌ مِّثْلُنَا تُرِيدُونَ أَن تَصُدُّونَا عَمَّا كَانَ يَعْبُدُ ءَابَآؤُنَا فَأْتُونَا بِسُلْطَـٰنٍ مُّبِينٍ

Their messengers said, "Can there be doubt about Allāh, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays you [i.e., your death] for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority [i.e., evidence]."
