*COMMANDERS OF THE MUSLIM ARMY AMONG THE COMPANIONS OF THE PROPHET ﷺ*
Al-Muthanna ibn Hārithah al-Shaybāni رحمه الله
"Allah bless the eyes of Rafi, how did he succeed
In finding the way from Qaraqir to Nawa?
Five days it had marched, when the army wept;
No human ever made such a journey before!"
[A soldier who took part in the march - Ibn Kathir, Al-Bidayah wan-Nihayah, Vol. 7 P. 10.]
At Hirah, in late May 634, Khalid رضي الله عنه opened the Caliph Abu Bakr's رضي الله عنه letter and read:
In the name of Allah, the Beneficent, the Merciful. From the slave of Allah, Atiq, son of Abu Quhāfah, [Although the Caliph is known to history as Abu Bakr رضي الله عنه, his actual name was Abdullah, and he had also been given the name of Atiq by the Prophet ﷺ.] to Khalid, son of Al Waleed. Peace be upon you.
I render praise unto Allah save whom there is no Allah, and invoke blessings on His Prophet, Muhammad, on whom be the blessings of Allah and peace.
March until you reach the gathering of the Muslims in Syria, who are in a state of great anxiety ...
Khalid رضي الله عنه read:
I appoint you commander over the armies of the Muslims and direct you to fight the Romans. You shall be commander over Abu Ubaidah and those with him.
Go with speed and high purpose, O Father of Sulaiman, and complete your task with the help of Allah, exalted be He. Be among those who strive for Allah.
Divide your army into two and leave half with Muthanna who shall be commander in Iraq. Let not more go with you than stay with him. After victory you shall return to Iraq and resume command.
Let not pride enter your mind, for it will deceive and mislead you. And let there be no delay. Lo, to Allah belongs all bounty and He is the dispenser of rewards. [Tabari Vol. 2, pp. 600, 605; Waqidi: Futuh, p. 14 (All references to Waqidi in the remainder of this book are from his Futuh-ush-Sham)]
Thus was Khalid رضي الله عنه appointed Commander-in-Chief of the Muslim forces in Syria. [Other versions of how Khalid assumed command in Syria suggest that he himself prevailed upon the other generals to let him command the army, or that the generals themselves appointed him commander on account of his military stature. These versions are not correct. Khalid رضي الله عنه was expressly appointed Commander-in-Chief in Syria by Caliph Abu Bakr رضي الله عنه]
Khalid رضي الله عنه now set about the preparations for his march. He explained the instructions of the Caliph to Muthanna رضي الله عنه, divided his army into two and handed over one half of it to Muthanna رضي الله عنه. But in the division of the army, Khalid رضي الله عنه tried to keep all the Companions of the Prophet ﷺ -the Emigrants and the Ansars, men held in special esteem by the soldiers. To this Muthanna objected vehemently. “I insist on a total execution of Abu Bakr's orders", he said. "I shall have half the Companions also, for it is by their presence that I hope to win victories." [Tabari: Vol. 2, p. 605]
Khalid رضي الله عنه saw the justice of Muthanna's رضي الله عنه claim. He revised the division to leave Muthanna رضي الله عنه a satisfactory share of the Companions, particularly as these included many of the finest officers of the army. This done, Khalid رضي الله عنه was ready for the march to Syria.
It was Abu Bakr's رضي الله عنه way to give his generals their mission, the geographical area in which that mission would be carried out, and the resources that, could be made available for that purpose. He would then leave it to his generals to accomplish their mission in whatever manner they chose. This is how he had launched Khalid رضي الله عنه into Iraq, and this is how he was now launching Khalid رضي الله عنه into Syria.
The Muslim forces had already conquered Hira and established control over the surrounding Arab-populated regions of Mesopotamia along the Euphrates River. The fall of Hira alarmed the Persian Empire, prompting the young Yazdegerd III to take the Muslim threat more seriously.
