Al-Baqarah 2:181

Faman baddalahu baAAda ma samiAAahufa-innama ithmuhu AAala allatheenayubaddiloonahu inna Allaha sameeAAun AAaleem

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.

Then, whoever changes it after he has heard it, its sin will only be on those who change it. Surely, Allah is All-hearing, All-knowing.
