The battalion of Basheer bin Sa’d The Prophet (a.
The battalion of Basheer bin Sa’d The Prophet (a.s.) sent Basheer bin Sa’d with thirty horsemen to the Banu Murrah in Fadak who fought him and killed all the men with him. Basheer was patient in fighting them. He fought [1] As-Seera an-Nabawiyyah by ibn Hisham, vol. 3 p. 418. courageously until he could escape them safely and go back to Medina. Then, the Prophet (a.s.) sent to them Ghalib bin Abdullah with some great companions among whom was Usamah bin Zayd and ibn Mas’ud.
Usamah fought against Mardas bin Nehik, and when he was able to kill him, Mardas said, “There is no god but Allah”. However, Usamah did not care for that and he killed the man. The companions blamed Usamah for that. The Prophet (a.s.) was too much distressed for that and he said to Usamah, “O Usamah, who is to you without ‘there is no god but Allah’?” Usamah felt great regret for the great sin he committed. [1] 5.
The battalion of Abu Hadrad Rifa’ah bin Qays and some men from the Banu Jusham bin Mo’awiya camped in a forest trying to gather some other people in order to fight against the Prophet (a.s.) and his followers. The Prophet (a.s.) sent for Abu Hadrad and other two Muslims and ordered them to deal with the trouble of Rifa’ah. They set out until they were near the camp of Rifa’ah and his men.
In the night, Abu Hadrad could kill Rifa’ah, and then he with his two companions went back to the Prophet (a.s.). [2] 6. The battalion of Amr bin al-Aas The Prophet (a.s.) sent Amr on the head of a battalion to mobilize the Arab tribes towards Sham. No fight took place during this expedition. Its task was just to call people to attack Sham. [1] As-Seera an-Nabawiyyah by ibn Hisham, vol. 3 p. 419. [2] Ibid., p. 422. 7.
The battalion of Zayd bin Harithah Zayd bin Harithah attacked, with a battalion, Wadi al-Qura in which there was a people from the Banu Fazarah. In this fight, Zayd was wounded. He took an oath that he would not sleep with his wife except after defeating the Banu Fazarah. He went back to the Prophet (a.s.) who made him the leader of an army that marched again towards the Banu Fazarah who were killed in this battle and the rest of them were taken prisoners.
[1] The mentioned above are some of the military tasks that the Prophet (a.s.) had sent to guide people to Islam or to defeat some groups of polytheists or unfaithful powers that were hostile to Islam and Muslims. There were other military tasks that we see it is not necessary to mention them all here.
