Expedition of Abu Qatadah ibn Rab'i al-Ansari,[5] to Khadirah (also spelt Khadrah), and also known as the Campaign of Khadrah[6][7] took place in November 629 AD, 8AH, 8th month, of the Islamic Calendar[8] In Sha‘ban month 8 A.H., news reached Muhammad of amassing troops by Bani Ghatafan, still outside the domain of Islam.
He urgently summoned Abu Qatadah and sent him at the head of 18 men to discipline the tribe.
[9][10] This was an expedition against the tribe of Khudra a sub-clan of Banu Ghatafan, which resulted in the capture of large amounts of flock.
After this expedition, due to Muhammad's increasing power, many tribes switched their allegiance and converted to Islam.
The Banu Sulaym also submitted themselves to Muhammad after previously fighting his followers in the Expedition of Ibn Abi Al-Awja Al-Sulami,[11] where most of the Muslims and Banu Sulaym who fought each other were killed.
