根据安拉在祂的经典中的表述，《古兰经》的降示曾经发生过两次不同的降示。理解这两次降示十分重要，这样才能消除《古兰经》和逊奈中用来描述《古兰经》降示的各种术语之间所表面呈现的矛盾。一方面，《古兰经》被描述为在斋月或在高贵之夜（Laylatul-Qadr，即定夜）整体降示；另一方面，它又被描述为在先知穆罕默德ﷺ去世前不久之前，持续地分段降示。

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).
