[Machine] The Quran was revealed in its entirety from the upper heaven to the lower heaven in one night, and then it was revealed gradually over the years. He (Prophet Muhammad) recited this verse: "So I swear by the positions of the stars" [Al-Waqi'ah 75]. He (Prophet Muhammad) said, "It was revealed in separate parts."
أُنْزِلَ الْقُرْآنُ فِي لَيْلَةِ الْقَدْرِ مِنَ السَّمَاءِ الْعُلْيَا إِلَى السَّمَاءِ الدُّنْيَا جُمْلَةً وَاحِدَةً ثُمَّ فُرِقَ فِي السِّنِينَ قَالَ وَتَلَا هَذِهِ الْآيَةَ {فَلَا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ} [الواقعة 75] قَالَ «نَزَلَ مُتَفَرِّقًا»
