Surah Al-Baqarah, ayah 181

فَمَنۢ بَدَّلَهُۥ بَعۡدَ مَا سَمِعَهُۥ فَإِنَّمَآ إِثۡمُهُۥ عَلَى ٱلَّذِينَ يُبَدِّلُونَهُۥٓۚ إِنَّ ٱللَّهَ سَمِيعٌ عَلِيمٞ ١٨١

Famam baddalahū ba'da mā sami'ahū fa innamā ithmuhū 'alal-ladhīna yubaddilūnahū innallāha samī'un 'alīm

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