As Salamu Alaikum wa Rahmatullahi wa Barakatuhu
As-Sawiq Invasion:
Two-pronged hostile activities were being independently conducted against the Prophet (Sallallahu 'Alayhi wa Sallam); plots and intrigues being hatched by Safwan bin Omaiyah, the hypocrites and Jews on the one hand, going on and on parallel lines with military hostilities being prepared by Abu Sufyan aiming at saving the face of his people and impressing on the other Arabs that Quraish was still a military power to be counted for. In the aftermath of Badr, Abu Sufyan was burning for revenge and took a solemn vow he would never bathe off impurity unless he h ad avenged himself on Muhammad (Sallallahu ‘Alayhi wa Sallam) and his followers. He set out at the head of 200 men towards Madinah but was not brave enough to attack it in broad daylight. He, instead resorted to acts of piracy that are performed in the dark. He infiltrated into the Prophet ’s town and went to see an old ally Huyai bin Akhtab, who was too cowardly to let him in, so he left for Salam bin Mashkam, chief of Bani Nadeer, a tribe of Jews. The Jew entertained and gave him a full account of the situation therein. Late at night he despatched a group of his men to raid Al-‘Uraid, a suburb of Madinah. There, the men felled and burnt the palm trees, killed two Muslims and then took swiftly to their heels.
On hearing the news, the Prophet (Sallallahu ‘Alayhi wa Sallam) gathered his men and set out at their heels, but could not catch them. The Muslims brought back the provisions (Sawiq, a kind of barley porridge) which the polytheists had thrown aside in order to lighten their loads and hasten their escape; hence this campaign was called As-Sawiq Invasion. It took place in Dhul-Hijjah 2 A.H., two months after the event of Badr.
Dhi Amr Invasion, Muharram, 3 A.H:
The Prophet’s (Sallallahu 'Alayhi wa Sallam) intelligence personnel reported that Banu Tha‘labah and Banu Muhârib were mustering troops with the aim of raiding the outskirts of Madinah. The Prophet (Sallallahu ‘Alayhi wa Sallam) at the head of 450 horsemen and footmen set out to handle this new situation. ‘Uthman bin ‘Affan (Radhi Allahu Anhu) was asked to dispose the affairs of the Muslims in Madinah. On their way, they captured a man who embraced Islam and acted as a guide for the army. When the enemies heard of the approach of the Muslims, they hurriedly dispersed in the mountains and disappeared. The Muslims encamped at a watering place called “Dhi Amr” for the whole of Safar 3 A.H. The Prophet (Sallallahu ‘Alayhi wa Sallam) aimed to impress upon the desert Bedouins in the area, that the Muslims were then powerful enough to cast fear and awe into the hearts of their enemies.
