You will not find a people who believe in Allāh and the Last Day having affection for those who oppose Allāh and His Messenger, even if they were their fathers or their sons or their brothers or their kindred. Those - He has decreed within their hearts faith and supported them with spirit1 from Him. And We will admit them to gardens beneath which rivers flow, wherein they abide eternally. Allāh is pleased with them, and they are pleased with Him - those are the party of Allāh. Unquestionably, the party of Allāh - they are the successful.

Tafsir
O Messenger! You will not find a people believing in Allah and in the Day of Judgement, who love and befriend those who regard Allah and His Messenger as enemies, even though these enemies of Allah and His messengers happen to be their fathers, sons, brothers, or tribe members they affiliate themselves to. This is because faith prevents them from befriending the enemies of Allah and His Messenger, and because the connection of faith is greater than all connections, so it is to be given priority at times of conflict. Those who do not befriend the enemies of Allah and His Messenger - even if they are their own relatives - are the ones in whose hearts Allah has established faith such that they do not waver, and has strengthened with His proof and light. He will also enter them on the Day of Judgement into everlasting gardens, under the palaces and trees of which rivers flow, and in which they shall live forever, without its luxuries ever finishing or them ever becoming extinct. Allah is pleased with them to a degree that He will never be displeased with them afterwards, and they are also pleased with Him because of Him having given them favours which will never finish, one of which is the ability to see Him may He be glorified. They are the party of Allah that fulfils whatever He commands and refrain from the things He does not allow. Know well that indeed, the party of Allah are the ones who will succeed by achieving their objective and remaining safe from their fears in the world and the afterlife.
