The Razwa of Bani Lahyan

The Bani Lahyan was the tribe that tricked the Muslims into sending large emissaries. And they then started killing the Sahab, and massacres took place. So this is now clearly called for. The Prophet Salaahu Alaihi Wasallam did not want to tell anybody where he's going. He didn't tell a single soul that when he left the city with 300 people, then he doubled back.
