Musnad Ahmad 26:270

'Abd al-Samad narrated to us, Hammad narrated to us, from 'Asim, from Zirr, from Ibn Mas'ud, that the Messenger of Allah (peace and blessings of Allah be upon him) was shown the nations at the season (of Hajj), and his nation was presented to him. He said: "Then my nation was shown to me, and their great number pleased me; they had filled the plain and the mountain. It was said to me: 'With these are seventy thousand who will enter Paradise without reckoning. They are those who do not seek cauterization, do not seek Ruqyah (incantations), do not practice augury (taking omens), and they rely upon their Lord.'" 'Ukkashah said: "O Messenger of Allah, pray to Allah to make me one of them." So he prayed for him. Then another man stood up and said: "O Messenger of Allah, pray to Allah to make me one of them." He said: "'Ukkashah has preceded you to it."
