Then whoever alters the bequest after he has heard it - the sin is only upon those who have altered it. Indeed, Allah is Hearing and Knowing.

فَمَنۢ بَدَّلَهُۥ بَعْدَمَا سَمِعَهُۥ فَإِنَّمَآ إِثْمُهُۥ عَلَى ٱلَّذِينَ يُبَدِّلُونَهُۥٓ إِنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌThen whoever alters the bequest after he has heard it - the sin is only upon those who have altered it. Indeed, Allah is Hearing and Knowing.
