the first people to take up arms against the muslims in the aftermath of uhud reverse were banu asad bin khuzaimah. "the intelligence corps" of madinah reported that talhah and salamah, sons of khuwailid have mustered some volunteers to fight the messenger of allâh [pbuh]. the prophet [pbuh] immediately despatched a 150-man-platoon of helpers and emigrants headed by abu salamah. the muslim leader took bani asad bin khuzaimah by surprise in their own homeland, neutralized their attempts, dispersed them and captured their cattle. on his return, abu salamah had an inflammation of a previous wound he sustained in uhud, and caused him to die soon after. this expedition took place on muharram 1st, 4 a.h.[za'd al-ma'ad 2/108]
