Sir William Muir On the Wednesday following...
Sir William Muir On the Wednesday following, Mohammed was seized with a violent headache and fever; but it passed off. The next morning he found himself sufficiently recovered to bind with his own hand upon the Flagstaff a banner for the army. He presented it to Usama with these words: 'Fight thou beneath this banner in the name of the Lord, and for His cause.
Thus thou shalt discomfit and slay the people that disbelieveth in the Lord.' The camp was then formed at Jorf; and the whole body of fighting men, not excepting even Abu Bakr and Umar, were summoned to join it. (The Life of Mohammed, London, 1877) Muhammad Husayn Haykal The Muslims did not stay long in Madinah following their return from the Farewell Pilgrimage in Makkah. The Prophet had immediately ordered the mobilization of a large army and commanded it to march on al-Sham.
He sent along with that army a number of the elders of Islam, the earliest Muhajirun, among whom were Abu Bakr and Umar. He gave the command of the army to Usama ibn Zayd ibn Harithah. (The Life of Muhammad, Cairo, 1935) The Prophet wished the army to leave Medina at once. But strangely, the army did not show any eagerness to obey him. Instead of obedience, the Prophet met resistance – from some of his companions!
Thenceforth, the Prophet had to grapple with two problems; one was to overcome his illness and the other was to overcome the resistance of his army. The last few days of his life on this earth were dominated by this two-pronged struggle. The senior members of the Quraysh bitterly resented the elevation of a boy of 18 over all of them, and that too, the son, not of a “high-born” Qurayshi, but of a former slave!
Therefore, instead of reporting to him for duty, many among them began to play truant and to temporize. Some among them were so disgruntled at the selection of Usama as their general that they openly expressed their displeasure. R.V.C. Bodley ...The veterans did not like the idea of attacking the still redoubtable Romans with a lad, who had little military experience, as their leader. Mohammed was, however, unmoved by the protests.
He was establishing the precedent, observed ever since among Moslems, that age and social standing do not necessarily make the best generals. He was ingraining in them the message of democracy which they were to carry to the world. Without discussing the nomination he summoned Osama to the mosque and handed him the banner of Islam with recommendation to bring it honor.
