The Family of Imran
إِنَّ أَوْلَى ٱلنَّاسِ بِإِبْرَٰهِيمَ لَلَّذِينَ ٱتَّبَعُوهُ وَهَـٰذَا ٱلنَّبِىُّ وَٱلَّذِينَ ءَامَنُوا۟ ۗ وَٱللَّهُ وَلِىُّ ٱلْمُؤْمِنِينَ
Indeed, the most worthy of Abraham among the people are those who followed him [in submission to Allah] and this prophet, and those who believe [in his message]. And Allah is the ally of the believers.

هَـٰٓأَنتُمْ هَـٰٓؤُلَآءِ حَـٰجَجْتُمْ فِيمَا لَكُم بِهِۦ عِلْمٌ فَلِمَ تُحَآجُّونَ فِيمَا لَيْسَ لَكُم بِهِۦ عِلْمٌ ۚ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ
Here you are - those who have argued about that of which you have [some] knowledge, but why do you argue about that of which you have no knowledge? And Allah knows, while you know not.
مَا كَانَ إِبْرَٰهِيمُ يَهُودِيًّا وَلَا نَصْرَانِيًّا وَلَـٰكِن كَانَ حَنِيفًا مُّسْلِمًا وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ
Abraham was neither a Jew nor a Christian, but he was one inclining toward truth, a Muslim [submitting to Allah]. And he was not of the polytheists.
وَدَّت طَّآئِفَةٌ مِّنْ أَهْلِ ٱلْكِتَـٰبِ لَوْ يُضِلُّونَكُمْ وَمَا يُضِلُّونَ إِلَّآ أَنفُسَهُمْ وَمَا يَشْعُرُونَ
A faction of the people of the Scripture wish they could mislead you. But they do not mislead except themselves, and they perceive [it] not.
يَـٰٓأَهْلَ ٱلْكِتَـٰبِ لِمَ تَكْفُرُونَ بِـَٔايَـٰتِ ٱللَّهِ وَأَنتُمْ تَشْهَدُونَ
O People of the Scripture, why do you disbelieve in the verses of Allah while you witness [to their truth]?
