According to Allaah’s statements in His Book, there were two distinct revelations of the Qur’aan which took place. It is important that these two revelations be understood in order to clear up the apparent contradictions in the various terms used in the Qur’aan and Sunnah to describe the Qur’aan’s revelation. On one hand, the Qur’aan is referred to as having been revealed in its totality in Ramadaan or on Laylatul-Qadr, the Night of Decree; while on the other hand, it is referred to as having been continuously revealed in segments up until just before the death of the Prophet (ﷺ).
