The Prophet Salallam's Assassination

Umayyib ibn Umayyah, his son had just been taken prisoner of war and his son was still in Medina as a POW. And he didn't have or he couldn't or he didn't want to pay the ransom. So Safwan took this golden opportunity, his father was Umayyah a rich man. He sharpened his sword and he poisoned it, such that if the tip had just entered into anybody's body, it would have been enough poison to die. The Prophet Salallahu Alaihi Wasallam then left Mecca without telling a single soul where he's going.
