Is it permissible to supplicate against the older brother who deprived his sibling of his inheritance and registered his share in his own name?

Depriving an heir of inheritance is an injustice and a major sin. It is permissible to supplicate against an oppressor to the extent of their wrongdoing, without exceeding that, but refraining from supplicating is better. The permissibility of supplicating against an oppressor is indicated by the Hadith of Abu Hurairah concerning the neighbor's complaint. Scholars have stated the permissibility of supplicating against an oppressor, even if one is not the wronged party, but it is preferable not to supplicate against them, and to forgive and be patient.
