Question: I stopped speaking to my older brother for a period of years, and that was [only] to avoid problems – so what is the ruling regarding that? And is what I did correct?
Response: It is not permissible for a person to cut off from his relative, because of what the Prophet (sal-Allaahu ‘alayhi wa sallam) said:
And it is obligatory upon the believer to maintain his ties of kinship, even if his relatives sever them, because the Prophet (sal-Allaahu ‘alayhi wa sallam) said:
And it is not permissible for him to respond in like with the relative who has severed ties with him; beware of severing ties with him, and instead continue to maintain ties with him. [Remember that] the upper hand is better than the lower hand, and so if he continues to maintain ties [of kinship] with him – despite this situation, then Allaah will grant him success over him.
