Sahl b. Sa'd reported Allah's Messenger ﷺ as saying, “The lord of the people on a journey is their servant,* and he who precedes them in service will not be preceded by them on account of any deed but martyrdom.” * This is said to mean either that the leader must look after the interests of his followers, or that even the humblest member who serves the others is rewarded by Allah as if he were the dealer. Baihaqi transmitted it in Shu'ab al-iman.
