صحيح البخاري

Narrated 'Ubada bin As-Samat:

I was among those Naqibs (selected leaders) who gave the Pledge of allegiance to Allah's Messenger. We gave the oath of allegiance, that we would not join partners in worship besides Allah, would not steal, would not commit illegal sexual intercourse, would not kill a life which Allah has forbidden, would not commit robbery, would not disobey (Allah and His Apostle), and if we fulfilled this pledge we would have Paradise, but if we committed any one of these (sins), then our case will be decided by Allah.
