His father ended up dying by his hands at the battle of Badr. Allah consoled him with the verse: “You will not find any people who believe in Allah and the Last Day loving those who resist Allah and His Messenger, even though they were their fathers or their sons or their brothers or their kindred. For such he has written faith in their hearts and strengthened them with a spirit from Himself.” (58:22)
