4:166 لَّٰكِنِ ٱللَّهُ يَشْهَدُ بِمَآ أَنزَلَ إِلَيْكَ أَنزَلَهُۥ بِعِلْمِهِۦ وَٱلْمَلَٰٓئِكَةُ يَشْهَدُونَ وَكَفَىٰ بِٱللَّهِ شَهِيدًا
But Allah bears witness by what He has revealed to you that He has revealed it with His knowledge, and the angels bear witness (also); and Allah is sufficient as a witness.
6:150 قُلْ هَلُمَّ شُهَدَآءَكُمُ ٱلَّذِينَ يَشْهَدُونَ أَنَّ ٱللَّهَ حَرَّمَ هَٰذَا فَإِن شَهِدُوا۟ فَلَا تَشْهَدْ مَعَهُمْ وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ وَهُم بِرَبِّهِمْ يَعْدِلُونَ
Say: Bring your witnesses who should bear witness that Allah has forbidden this, then if they bear witness, do not bear witness with them; and follow not the low desires of those who reject Our communications and of those who do not believe in the hereafter, and they make (others) equal to their Lord.
Said they: Then bring him before the eyes of the people, perhaps they may bear witness.
And they who do not bear witness to what is false, and when they pass by what is vain, they pass by nobly.
