Sahih Bukhari Volume 008, Book 076, Hadith Number 549.
Narated By Ibn 'Abbas : The Prophet said, "The people were displayed in front of me and I saw one prophet passing by with a large group of his followers, and another prophet passing by with only a small group of people, and another prophet passing by with only ten (persons), and another prophet passing by with only five (persons), and another prophet passed by alone. And then I looked and saw a large multitude of people, so I asked Gabriel, "Are these people my followers?' He said, 'No, but look towards the horizon.' I looked and saw a very large multitude of people. Gabriel said. 'Those are your followers, and those are seventy thousand (persons) in front of them who will neither have any reckoning of their accounts nor will receive any punishment.' I asked, 'Why?' He said, 'For they used not to treat themselves with branding (cauterization) nor with Ruqya (get oneself treated by the recitation of some Verses of the Qur'an) and not to see evil omen in things, and they used to put their trust (only) in their Lord." On hearing that, 'Ukasha bin Mihsan got up and said (to the Prophet), "Invoke Allah to make me one of them." The Prophet said, "O Allah, make him one of them." Then another man got up and said (to the Prophet), "Invoke Allah to make me one of them." The Prophet said, 'Ukasha has preceded you."
