Allah commands shunning the disbelievers, even if they are one's parents or children, and prohibits taking them as supporters if they choose disbelief instead of faith. Allah warns,

i(You will not find any people who believe in Allah and the Last Day, making friendship with those who oppose Allah and His Messenger, even though they were their fathers or their sons or their brothers or their kindred (people). For such He has written (predetermined) faith in their hearts, and strengthened them with a Ruh (proof, light and true guidance) from Himself. And He will admit them to Gardens (Paradise) under which rivers flow.) ﴿58:22﴾ Al-Hafiz Al-Bayhaqi recorded that `Abdullah bin Shawdhab said, "The father of Abu `Ubaydah bin Al-Jarrah was repeatedly praising the idols to his son on the day of Badr, and Abu `Ubaydah kept avoiding him. When Al-Jarrah persisted, his son Abu `Ubaydah headed towards him and killed him. Allah revealed this Ayah in his case,

(25. Truly, Allah has given you victory on many battlefields, and on the day of Hunayn (battle) when you rejoiced at your great number, but it availed you naught and the earth, vast as it is, was straitened for you, then you turned back in flight). (26. Then Allah did send down His Sakinah (tranquillity) on His Messenger, and on the believers, and sent down forces (angels) which you saw not, and punished the disbelievers. Such is the recompense of disbelievers). (27. Then after that Allah will accept the repentance of whom He wills. And Allah is Oft-Forgiving, Most Merciful.)
