Musnad Abu Ya'la al-Mawsili 152:220

Abu Khaythama narrated to us, Yazid bin Harun narrated to us, al-Mas'udi narrated to us, from al-Hasan bin Sa'd, from 'Abdah al-Nasri, from Abdullah bin Mas'ud, who said: The Messenger of Allah (ﷺ) said: "Verily, Allah has not prohibited a prohibition except that He knew that someone among you would eventually approach it. Behold, I am holding onto your waistbands to keep you from the Fire, lest you fall into it like the falling of moths, flies, or locusts."
