The word of the Mighty and Sublime { You will not find people who believe in Allah and the last day to be affectionate towards anyone who opposes Allah and His Messenger … } [Al-mujadilah 22] . He is making known that the faith of Believers is spoiled by affection with Disbelievers [Kuffar], and that anyone who is a Believer can not be close with anyone who has disbelieved.
