2:182
فَمَنْ خَافَ مِن مُّوصٍ جَنَفًا أَوْ إِثْمًا فَأَصْلَحَ بَيْنَهُمْ فَلَآ إِثْمَ عَلَيْهِ ۚ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
faman khāfa min mūṣin janafan aw ith'man fa-aṣlaḥa baynahum falā ith'ma ʿalayhi inna l-laha ghafūrun raḥīmun
But if anyone knows that the testator has made a mistake, or done wrong, and so puts things right between the parties, he will incur no sin: God is most forgiving and merciful.
But he who fears from a testator some unjust act or wrong-doing, and thereupon he makes peace between the parties concerned, there shall be no sin on him. Certainly, Allâh is Oft-Forgiving, Most Merciful.
