Abu lshaq said: I asked Zaid b. Arqam: In how many military expeditions have you participated with Allah's Messenger (may peace be upon him)? He said: In seventeen (expeditions). He (Abu Ishaq) said: Zaid b. Arqam reported to me that Allah's Messenger (may peace be upon him) had led nineteen expeditions.
