Safrana Ibn Umeya and the Battle of U'd

Saria of Khorada took place a few months before U'd, most likely in Rabirul Awal. This was an important stepping stone to the actual battle of U'd. Safrana ibn Umeya who had been placed in charge of this year's caravan said Muhammad and his companions have blocked our passages. If we take the sea route close to the ocean most of them have already given their allegiance to Muhammad  - so what do we do? "This shows us that Islam was spreading," he says.
