Abdullah bin Abbas reported,

The Prophet ﷺ set out with a group of his companions heading for the market of Ukaz. Now the devils had been barred from the news of heaven, and shooting stars had been sent against them, so they returned to their own people, who asked them, "What is the matter with you?"They replied, "We have been barred from the news of heaven, and shooting stars have been sent against us."Their people said, "Nothing has come between you and the news of heaven except some event that has occurred. So travel through the east and west of the earth and find out what it is that has come between you and the news of heaven."Those who had set off toward Tihamah came upon the Prophet ﷺ at Nakhlah, while he was on his way to the market of Ukaz, leading his companions in the Fajr prayer. When they heard the Quran, they listened closely to it and said, "By Allah, this is what has come between you and the news of heaven."At that point they went back to their people and said, "Our people, 'We have heard a wondrous Quran that guides to right conduct, so we have believed in it, and we will never associate anyone with our Lord'" [Jinn 72:1–2].So Allah revealed to His Prophet ﷺ, "Say, it has been revealed to me" [Jinn 72:1]. What was revealed to him was the speech of the jinn.

عن ابن عباس قال

انطلق النبي ﷺ في طائفة من أصحابه عامدين إلى سوق عكاظ، وقد حيل بين الشياطين وبين خبر السماء، وأرسلت عليهم الشهب، فرجعت الشياطين إلى قومهم، فقالوا: مالكم؟ فقالوا: حيل بيننا وبين خبر السماء، وأرسلت علينا الشهب. قالوا: ما حال بينكم وبين خبر السماء إلا شيء حدث، فاضربوا مشارق الأرض ومغاربها، فانظروا ما هذا الذي حال بينكم وبين خبر السماء، فانصرف أولئك الذين توجهوا نحو تهامة إلى النبي ﷺ وهو بنخلة عامدين إلى سوق عكاظ، وهو يصلي بأصحابه صلاة الفجر، فلما سمعوا القرآن استمعوا له، فقالوا: هذا والله الذي حال بينكم وبين خبر السماء، فهنالك حين رجعوا إلى قومهم، وقالوا: ياقومنا{إنا سمعنا قرءانا عجبا يهدى إلى الرشد فءامنا به ولن نشرك بربنا أحدا}[الجن: ٢]، فأنزل الله على نبيه ﷺ: {قل أوحي إلى} وإنما أوحي إليه قول الجن.
