Ibn ‘Abbās said, “The entirety of Sūrah al-An’ām was revealed in Makkah at night, accompanied by seventy thousand angels, raising their voices around it in glorification of Allah.” Reference: At-Tabarani 12/215. There are many other variations of this hadith from different companions, including Abdullah b. Masʿūd, Abdullah b. Umar, Asmā’, Ali, Ubayy, but most of their chains contain weaknesses.
عنِ ابنِ عبَّاسٍ ، قالَ : نزلتْ سورَةُ الأنعامِ بمَكَّةَ ليلًا جملةً ، حولَها سبعونَ ألفَ ملَكٍ يجأرونَ حولَها بالتَّسبيحِ.
