Shiavault - a Vault of Shia Islamic Books Prophethood and the Prophet of Islam Revelation and Preservation of Quran Quran is a heavenly book and the word of God Almighty. Lofty matters and facts of Quran have come down in the form of Arabic words and sentences which were sent down to the illuminated heart of the Prophet of Islam through Jibraeel.
Verses of Quran were revealed on the Prophet of Islam in a period of 23 years on different appropriate occasions in journey and at home and in war as well as peace. Sometimes one verse, sometimes a number of verse and at other times even a whole chapter was revealed at a time. The Holy Quran has 114 chapters and all of them except Surah Taubah begin with the formula: In the name of Allah, the Beneficent, the Merciful. Every chapter is composed of a number of verses.
The big chapters are called as the long chapters and the small chapters are called as the short chapters. A number of chapters were revealed in Mecca or its surroundings and they are known as the Meccan chapters and others were revealed in Medina and its surroundings and they are Medinan chapters.
The Holy Prophet (S) paid special attention in order to preserve the collection of Quran and to prevent it from interpolation and alteration, and that is why he performed the following three actions: Whenever a verse was revealed on the illuminated heart of the Prophet, he recited it immediately and stored it in his memory, never forgetting it, because his infallibility prevented him from forgetting it or making a mistake in it.
Although the Holy Prophet (S) had never attended a school he knew the whole Quran by heart and he recited it in the sequence of its revelation. He was infallible and immune from mistakes in receiving it from Jibraeel, its preservation and its conveyance.
