Expedition of Ghalib ibn Abdullah al-Laithi (Al-Kadid)

Expedition of Ghalib ibn Abdullah al-Laithi to Al-Kadid took place in May 629 AD, 8AH, 1st month, of the Islamic Calendar, Or according to other sources May 628 AD, 7AH, 3rd Month.

Expedition
A platoon headed by Ghalib bin ‘Abdullah Al-Laithi in Safar or in Rabi‘ Al-Awwal 7 A.H, Muhammad sent Ghalib ibn Abdallah al-Laythi, with between 10-15 men to raid the Banu al-Mulawwih at al-Kadid.

According to the Abu Dawud Hadith collection, when the Muslims arrived at al-Kadid they met a man, al-Harith ibn Malik and took him as a prisoner. He informed Ghalib that he had come to embrace Islam. But he chained him up for safety reasons.

The tribe was attacked and taken by surprise. The Muslims managed to kill a large number of the enemy soldiers and captured a great deal of booty. A large army of polytheists then pursued the Muslims, but heavy floods hindered the pursuit, and the Muslims managed to escape in safety.

According to Ibn Sa'd and Tabari, based on an account through Ibn Ishaq, who was told by a man from the Aslam tribe, the password used by Muslims to recognize one another while fighting at night was: Amit Amit (kill kill, in arabic ) '''[Ibn Sa'd, Kitab al-tabaqat al-kabir, Volume 2, Pg 156]

The Muslim Scholar Saifur Rahman al Mubarakpuri suggest that the reason for the attack was that the Banu Mulawwih were being provocative (without further details), whereas the Non Muslim historian Sir William Muir claims the reason for the attack is unknown.

Islamic primary sources
The event in also mentioned in the Sunni Hadith collection Abu Dawud as follows:

The Apostle of Allah (peace_be_upon_him) sent Abdullah ibn Ghalib al-Laythi along with a detachment and I was also with them. He ordered them to attack Banu al-Mulawwih from all sides at al-Kadid. So we went out and when we reached al-Kadid we met al-Harith ibn al-Barsa al-Laythi, and seized him. He said: I came with the intention of embracing Islam, and I came out to go to the Apostle of Allah (peace_be_upon_him). We said: If you are a Muslim, there is no harm if we keep you in chains for a day and night; and if you are not, we shall tie you with chains. So we tied him with chains.
