It is narrated from Sayyiduna Usayd bin Hudayr (may Allah be pleased with him) that he said: "One night I was praying when suddenly I saw a light like lamps descending from the sky. When I saw this, I fell down in prostration. Then I mentioned it to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "O Abu Atik! Why did you not carry on (that is, continue your recitation in the prayer)?" He said: "When I saw it, nothing was in my power except to fall down in prostration." The Messenger of Allah (peace and blessings be upon him) said: "Had you carried on, you would have seen wonders. Those were the angels descending (to listen) to the Qur'an."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Qatadah (may Allah have mercy on him) except Hisham, and no one from Hisham except Mu'adh; Ishaq bin Rahwayh (may Allah have mercy on him) is alone in narrating it."
