Another distinctive feature of Islam is that it not only proclaims its universal character, but also lays claims to being eternal, and it then proceeds to fulfil the preconditions of such a claim, for instance, a Message can be eternal only if it is complete and perfect in every aspect, and also guaranteed with regard to the verity of its contents. In other words, its revealed Books should bear divine guarantee against human revision and tampering. In so far as the teachings of the Holy Quran are concerned, the Almighty Himself claims in it:
I have this day perfected your faith for you in every way and, having completed My bounty upon you, have chosen for you Islam as religion.1
1 The Holy Quran 5:4.
