Lit., "between you" - i.e., "to induce you to be more tolerant of one another": evidently an allusion to the bitterness which stands in the way of an understanding between the various sects and schools of thought in all revealed religions.
I.e., because of this breach of the original unity of men's faith in the One God.
How beautifully the mission of Islam is commended in this verse! (1) The more sectarianism and division there is in the world, the more need is there for the Gospel of Unity. (2) It must steadfastly pursue its way. (3) It must not be deflected by worldly or political motives. (4) Its faith must be directly in Allah and in Allah's Revelation. "The Book" mentioned here covers all the revelations sent by Allah to His prophets. (5) it must judge justly between warring factions, as the Religion of Peace and Unity.
The Mission of Islam is further described. (6) The God whom it preaches is not an exclusive God: He is the Lord of the Worlds: to any given person, of whatever faith, 'He is your Allah, as well as mine.' (7) Our Faith is not a question of words; it is deeds which decide; each one of us has personal responsibility for his own conduct. (8) There is no cause of contention whatever, when we preach Unity, Truth, and the Hereafter. (9) If you have doubts, the final arbiter is Allah, and His pleasure is our Goal.
