4541 Allah's Religion is the same in essence, whether given, for example, to Noah, Abraham, Moses, or Jesus, or to our Prophet. The source of unity is the revelation from Allah. In Islam it is "established" as an institution, and does not remain merely a vague suggestion. 4542 Faith, Duty, or Religion, is not a matter to dispute about. The formation of sects is against the very principle of Religion and Unity. What we should strive for is steadfastness in duty and faith, and unity among mankind. 4543 Unity, unselfishness, love for Allah and man—these things are inconsistent with selfish aggrandizement, unjust suppression of our fellow-creatures, false worship, and false conduct to our brethren. Hence the Gospel of Unity, though it is in complete accord with the pure pattern after which Allah made us, is yet hard to those who love self and falsehood. But Grace is free to all, and in His wise Plan. He will specially select Teachers to show the Way to humanity, and no one who turns to Him will lack guidance.
