فَمَنۡ خَافَ مِن مُّوصٖ جَنَفًا أَوۡ إِثۡمٗا فَأَصۡلَحَ بَيۡنَهُمۡ فَلَآ إِثۡمَ عَلَيۡهِۚ إِنَّ ٱللَّهَ غَفُورٞ رَّحِيمٞ ١٨٢
But if one fears from the bequeather [some] error or sin and corrects that which is between them [i.e., the concerned parties], there is no sin upon him. Indeed, Allāh is Forgiving and Merciful.
Translation: Saheeh International (English)
Each word's meaning and sound
Whoever knows that there is an error in judgement from the person who made the will, or that there is some injustice in it, and advises the person and rectifies the wrong, and reconciles between those who are in disagreement about it, then there is no blame on them; rather they are rewarded for putting things right. Allah is Forgiving towards whomever of His servants repents to Him, and is Compassionate with them.
