It has been narrated on the authority of Salama who said:I joined seven military expeditions led by the Messenger of Allah himself (ﷺ), and nine expeditions which he sent out once under Abu Bakr and once under Usama b. Zaid

The (foregoing) tradition has also been narrated on the authority of Hatim through the same chain of transmitters with the difference that according to this version both these types of expeditions were seven in number
