Expedition of Qatan

The Expedition of Katan, was the first Raid on the Banu Asad bin Khuzaymah tribe, which occurred directly after the Battle of Hamra al-Asad in the year 4 A.H of the Islamic calendar. The expedition was ordered by Muhammad after he received intelligence that some members of the Banu Asad bin Khuzaymah were planning to attack Medina.

Background
Banu Asad ibn Khuzaymah tribe (not to be confused with the Banu Asad tribe), were the residents of Katan, in the vicinity of Fayd, was a powerful tribe connected with the Quraysh. They resided near the hill of Katan in Nejd. Muhammad, purportedly, received intelligence reports that they were planning a raid on Medina. So he dispatched a force of 150 men under the leadership of Abu Salama `Abd Allah ibn `Abd al-Asad to make a sudden attack on this tribe. On the first day of Muharram.

Raid
When the Muslims arrived at the site the tribe members fled and the Muslims found three herdsmen with a large herd of camels and goats. Then the booty, along with the three captives, was brought to Medina.

As per Islamic rule on plunder, all the movable booty must be taken out and removed from the site of plunder. It is unlawful, according to Islamic rule, not to take possession of infidel wealth after a successful plunder.

On the rule on Ghanimah, (plunder), the Dictionary of Islam writes, "If the Imam, or the leader of the Muslim army, conquers a country by force of arms, he is at liberty to leave the land in possession of the original proprietors, provided they pay tribute, or he may divide it amongst the Muslims; but with regard to movable property, it is unlawful for him to leave it in possession of the infidels, but he must bring it away with the army and divide it amongst the soldiers". For this reason, the goats were taken back to Medina (as they are movable objects).

Abu Salamah had an inflammation from a previous wound, and he died.

The 2nd raid of the Banu Asad tribe took place almost 3 years later.
