Musnad Ahmad 31:815

Ya'qub narrated to us, my father narrated to us, from Ibn Ishaq, who said: Yazid ibn Abdullah ibn Qusayt narrated to me, from 'Ata' ibn Yasar, or his brother Sulayman ibn Yasar, from Abu Sa'id al-Khudri, who said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, while he was addressing the people from his pulpit, saying: "O people, I was shown the Night of Decree, then I was made to forget it. And I saw that on my two arms were two bracelets of gold, so I disliked them, and I blew upon them, and they flew away. So I interpreted them as these two liars: the master of Yemen and the master of Yamama."
