It is said that Quran was written in response: "You will not find a people who believe in Allah and the Last Day having affection for those who oppose Allah and His Messenger, even if they were their fathers or their sons or their brothers or their kindred..."
(Al-Anfal: 73) “Kamu tidak akan mendapati sesuatu kaum yang beriman kepada Allah dan hari akhirat, saling berkasih sayang dengan orang-orang yang menentang Allah dan RasulNya, sekalipun orang-orang itu bapak-bapak, atau anak-anak atau saudara-saudara ataupun keluarga mereka.”
