Ahsanallahu Ilaikum ustadh, my maternal uncle lies against us, slanders us, hates the salafis (out of misunderstanding probab.), and almost made our dad lose his job and got him demoted, and works for a very evil, corrupt political party. Due to him being evil company, how to mantain kinship?

Ustadh AbdulAziz al-Haqqan
On Eid give salam, and on occasions, no need to give him the chanve to harm you.
