Juz 21 opens with

۞ وَلَا تُجَٰدِلُوٓا۟ أَهْلَ ٱلْكِتَٰبِ إِلَّا بِٱلَّتِى هِىَ أَحْسَنُ إِلَّا ٱلَّذِينَ ظَلَمُوا۟ مِنْهُمْ ۖ وَقُولُوٓا۟ ءَامَنَّا بِٱلَّذِىٓ أُنزِلَ إِلَيْنَا وَأُنزِلَ إِلَيْكُمْ وَإِلَٰهُنَا وَإِلَٰهُكُمْ وَٰحِدٌۭ وَنَحْنُ لَهُۥ مُسْلِمُونَ

And do not argue with the People of the Scripture except in a way that is best, except for those who commit injustice among them, and say, "We believe in that which has been revealed to us and revealed to you. And our God and your God is one; and we are Muslims [in submission] to Him."

Juz 21 closes with

يَٰنِسَآءَ ٱلنَّبِىِّ مَن يَأْتِ مِنكُنَّ بِفَٰحِشَةٍۢ مُّبَيِّنَةٍۢ يُضَٰعَفْ لَهَا ٱلْعَذَابُ ضِعْفَيْنِ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًۭا

O wives of the Prophet, whoever of you should commit a clear immorality - for her the punishment would be doubled two fold, and ever is that, for Allah, easy.
