Compromise with the enemy from the perspective of the Quran

Indeed those who said, “Allah is our Lord” and remained firm upon it – upon them descend the angels, (saying), “Do not fear nor grieve, and be happy for the Paradise which you are promised”. “We are your friends in the life of this world and in the Hereafter; in it for you is all that you may wish for, and for you is all what you ask”. “The hospitality of the Oft Forgiving, Most Merciful”. (fosselat, 30 – 32)
