Musnad Ahmad 26:672

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from 'Umarah, from 'Abd al-Rahman ibn Yazid, from 'Abdullah, and he mentioned its meaning. Then it was revealed: "And you were not covering yourselves, lest your hearing, your sight, and your skins should testify against you" [Fussilat: 22], up to His saying: "So you became among the losers" [Fussilat: 23].
