It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that concerning the saying of Allah Almighty, "Indeed, We sent it down on the Night of Decree" [Surah al-Qadr: 1] , he said: The Noble Qur'an was sent down complete, all at once, on the Night of Decree to the lowest heaven, and it was arranged in the manner of the positions of the stars. Then Allah Almighty kept sending down parts of it to His Messenger (peace and blessings be upon him), one after another, as needed. The narrator says: The disbelievers said: "Why was the Qur'an not sent down to him all at once? Thus (it is), that We may strengthen your heart thereby, and We have revealed it in stages" [Surah al-Furqan: 32] . This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
