The Battle of Badr

The Prophet SallAllahu Alaihi Wasallam knew that the caravan Abu Sufyan is going northwards towards Syria. The concept of targeting caravans, this is something that goes back even before this. We have a rough idea that occurred the first year after the Hijra. When exactly we don't know. Shows us that the targeting of the caravan was something that even the Ansar were thinking about not just the Muahajulun.
