Qur'ani ilifunuliwa kwa Nabii Muhammad (ﷺ) kwa sehemu sehemu katika miaka ishirini na tatu ya unabii wake. Kila tatizo lilipotokea, au kila Mwenyezi Mungu alipotaka kumpa Nabii (ﷺ) na wafuasi wake ushauri maalum, Mwenyezi Mungu alimtuma Malaika Jibril pamoja na sehemu ya Qur'ani, ambayo alimsomea Nabii (ﷺ). Hivyo, Qur'ani haikufunuliwa yote kwa mara moja katika umbo lake kamili kama vitabu vya awali vya wahyi, bali ilifunuliwa kwa sehemu katika kipindi cha muda.

The Qur’aan was revealed to Prophet Muhammad (ﷺ) in sections throughout the twenty-three years of his prophethood. Whenever a problem arose or whenever Allaah wanted to give the Prophet (ﷺ) and his follower’s special advice, Allaah would send angel Jibreel with a part of the Qur’aan, which he would recite to the Prophet (ﷺ). Thus, the Qur’aan was not revealed all at once in its complete form like the earlier books of revelation, but in parts over a period of time.
