they set out burning with indignation, motivated by a horrible desire for revenge and exterminating anyone that might jeopardize the routes of their caravans:

"…boastfully and to be seen of men, and hinder (men) from the path of allâh. " [al-qur'an 8:47]

or as the prophet [pbuh] said:

"o allâh these are the haughty and conceited; they have come defying allâh and defying his messenger."

they moved swiftly northward to badr. on the way they received another message from abu sufyan asking them to go back home because the caravan had escaped the muslims.
