All perfect praise be to Allah, The Lord of The Worlds, and may His peace and blessings be upon our Prophet Muhammad and upon all of his family and companions.

The inheritance system is described in details by Allah, The Exalted in both, the Holy Quran and Prophetic Sunnah whereas a Muslim is called so because he fully submitted with Allah ordainments with heart and soul and acts accordingly, for Allah, The Exalted, Said (What means): "But nay, by thy Lord, they will not believe (in truth) until they make thee judge of what is in dispute between them and find within themselves no dislike of that which thou decidest, and submit with full submission." [An-Nisa'/59].

Therefore, it is impermissible for your (Questioner) brother to be angry because you inherit your lawful share out of the inheritance, as his act considered a refusal of Allah's ordainment and breaking off ties of kinship.

Thus, the latter reasons are considered of the major sins whereas your brother (who committed them) might be doomed in this life and in the Hereafter.

On the other hand, you should treat him with kindness but to observe reciprocity departure, since Allah, The Exalted, Said (What means) :"Nor can goodness and Evil be equal. Repel (Evil) with what is better: Then will he between whom and thee was hatred become as it were thy friend and intimate!." [Fussilat/34].

In conclusion, there is no harm upon you for having your legitimate share out of your father's inheritance. And Allah Knows Best.
