[Machine] In His statement, "Indeed, We sent it down during the Night of Decree", it is said that the Qur'an was revealed all at once to the heavens of the world and it was positioned with the stars. Allah would send it to His Messenger ﷺ bit by bit in intervals. Allah said, "And those who disbelieved say, "Why was the Qur'an not revealed to him all at once?" Thus [it is] that We may strengthen thereby your heart. And We have spaced it distinctly."
فِي قَوْلِهِ ﷻ {إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ} [القدر 1] قَالَ أُنْزِلَ الْقُرْآنُ فِي لَيْلَةِ الْقَدْرِ جُمْلَةً وَاحِدَةً إِلَى سَمَاءِ الدُّنْيَا وَكَانَ بِمَوْقِعِ النُّجُومِ وَكَانَ اللهُ ﷻ يُنَزِّلُهُ عَلَى رَسُولِهِ ﷺ بَعْضُهُ فِي أَثَرِ بَعْضٍ فَقَالَ اللهُ ﷻ {وَقَالَ الَّذِينَ كَفَرُوا لَوْلَا أُنْزِلَ عَلَيْهِ الْقُرْآنُ جُمْلَةً وَاحِدَةً كَذَلِكَ لِنُثَبِّتَ بِهِ فُؤَادَكَ وَرَتَّلْنَاهُ تَرْتِيلًا}
