Forgiving others and seeking forgiveness from Allah.
These verses are grouped by theme as a starting point — not as standalone rulings. A verse takes on its full meaning only in context: the verses before and after, the occasion of revelation (asbāb al-nuzūl) and the explanation of the scholars. So read each verse in full via the tafsir, and consult a qualified scholar when in doubt.
ٱلَّذِينَ يُنفِقُونَ فِى ٱلسَّرَّآءِ وَٱلضَّرَّآءِ وَٱلْكَٰظِمِينَ ٱلْغَيْظَ وَٱلْعَافِينَ عَنِ ٱلنَّاسِ ۗ وَٱللَّهُ يُحِبُّ ٱلْمُحْسِنِينَ
Three traits of the muḥsinīn: spending, restraining anger, forgiving.
وَلَا يَأْتَلِ أُو۟لُوا۟ ٱلْفَضْلِ مِنكُمْ وَٱلسَّعَةِ أَن يُؤْتُوٓا۟ أُو۟لِى ٱلْقُرْبَىٰ وَٱلْمَسَٰكِينَ وَٱلْمُهَٰجِرِينَ فِى سَبِيلِ ٱللَّهِ ۖ وَلْيَعْفُوا۟ وَلْيَصْفَحُوٓا۟ ۗ أَلَا تُحِبُّونَ أَن يَغْفِرَ ٱللَّهُ لَكُمْ ۗ وَٱللَّهُ غَفُورٌۭ رَّحِيمٌ
Logical appeal: do you not want Allah to forgive you in return?
خُذِ ٱلْعَفْوَ وَأْمُرْ بِٱلْعُرْفِ وَأَعْرِضْ عَنِ ٱلْجَٰهِلِينَ

وَمَا خَلَقْنَا ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَمَا بَيْنَهُمَآ إِلَّا بِٱلْحَقِّ ۗ وَإِنَّ ٱلسَّاعَةَ لَءَاتِيَةٌۭ ۖ فَٱصْفَحِ ٱلصَّفْحَ ٱلْجَمِيلَ
“Turn away with a graceful forgiveness” — no reproach or bitterness.
وَجَزَٰٓؤُا۟ سَيِّئَةٍۢ سَيِّئَةٌۭ مِّثْلُهَا ۖ فَمَنْ عَفَا وَأَصْلَحَ فَأَجْرُهُۥ عَلَى ٱللَّهِ ۚ إِنَّهُۥ لَا يُحِبُّ ٱلظَّٰلِمِينَ
Forgiveness + reconciliation — the reward lies with Allah.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّ مِنْ أَزْوَٰجِكُمْ وَأَوْلَٰدِكُمْ عَدُوًّۭا لَّكُمْ فَٱحْذَرُوهُمْ ۚ وَإِن تَعْفُوا۟ وَتَصْفَحُوا۟ وَتَغْفِرُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌ
Specifically about forgiving spouses and children who oppose you.
