Public treasury in the tune of the Holy Prophet
In the time of the Holy Prophet there was no public treasury. Whatever revenues or other amounts were received these were distributed immediately. There were no salaries to be paid, and there was no State expenditure. As such the need of a treasury to keep a reserve at public level was not felt.

Public treasury in the time of Abu Bakr
In the time of Abu Bakr as well there was no treasury. A separate building was kept aside as treasury, but as all money was distributed immediately on receipt, the treasury generally remained locked up. At the time of the death of Abu Bakr, there was only one dirham in the public treasury.

Public treasury during the caliphate of Umar

In the early days of Islam there was no standing army. On the occasion of any battle contingents were raised from the various tribes, and such contingents were disbanded when the battle was over. No regular salaries were paid to those who fought. Those who took part in a battle were compensated by the distribution of the spoils of war among them. Organization of the army as a State department

The army was organized as a State department under Umar. A register of male adults who could be called to war was prepared tribewise, and a scale of salaries was fixed. All registered men were divided into two categories, those who formed the standing army, and those who lived in their home,, but were liable to be called to colors whenever necessary.

Organization at the battlefield
On the battlefield the army operated in six wings, namely: Qalb, the center Maqadamah, the vanguard Maunanah, the right wing Alaisarah, the left wing Saqah, the rear Rid, extreme rear.

Other Components
Other components of the army were: Talaych or patrols who kept watch over the movements of the enemy; Ra 'id or foraging parties; Rukban or the camel corps Farsan or the cavalry; Ralil or the infantry Ramat or the archers.

War weapons
Catapults were used for siege operations.

Dabbabah was a wooden tower which moved on wheels and consisted of several stories. It was used for siege operations.

Walls were Pierced by stone throwers and wall piercers.

Reporting and espionage
Reporters were attached to every unit who kept the Caliph fully informed about the military operation. There was a separate department for espionage, who procured intelligence about the movements and activities of the enemy.

Pattern of political administration
Uthman maintained the pattern of political administration as it stood under Umar. The country was divided into twelve provinces. These were Madina, Makkah, Yemen, Kufa, Basra, Jazira, Fars, Azarbauan, Khurasan, Syria, Egypt and North Africa. Under Umar Egypt was divided into two provinces, Upper and Lower Egypt. Uthman made Egypt one province. Uthman created a new province for North Africa. Under Umar Syria was divided into two provinces. Uthman made Syria one province.

Administrative organization
Each province was under the charge of a Governor or Wali. The Governor was in charge of civil as well as military administration. He was assisted by Katib, the Chief Secretary; Katib -i- Diwan-Secretary Defense; Sahib-i-Kharaj - Revenue Collector; Sahib-ul-Ahdath-Inspector General of Police; Sahib- i- Bait-ul- Mal-Treasury Officer; and Qadi-Chief Judge.

The Governors were appointed by the Caliph. Every appointment was made in writing. At the time of appointment an instrument of instructions was issued with a view to regulating the conduct of Governors. On assuming office, the Governor was required to assemble the people in the main mosque, and read the instrument of instructions before them.

One of the main allegations against Uthman was that he had appointed his relatives as Governors. Another allegation was that he exercised little check over the Governors.

Social revolution of Islam
Islam revolutionized social life in Arabia. Islam created new social values. The Holy Prophet set the pattern of conduct for the Islamic society. He was the embodiment of all the social values for which Islam stood. The Holy Prophet disciplined the Muslims into a solid community conspicuous for its piety, bravery, unity, and high social and moral values. After the Holy Prophet Abu Bakr and Umar carried forward the mission of the Master, and promoted the social values of Islam.

Muslim society under Uthman

Islam stood for social discipline and social solidarity. The Muslims were enjoined by Islam to be a disciplined people and obey those in authority among them. The Muslims were required to maintain social solidarity, and preserve unity in their ranks. During the caliphate of Uthman the Muslims lost their sense of discipline, and they also lost their strength of solidarity. Certain sections grew among the Muslims who made it a point to carry on propaganda against authority. Uthman took steps to redress the legitimate grievances of the people, but there was no slackening in the virulence of the vilification campaign against Uthman and his government.

Islam stood for unity in the ranks of the Muslims. During the caliphate of Uthman the Muslim society fell a prey to disunity, and things came to be looked at from the partisan point of view rather than from the point of view of the interests of the Muslim community as a whole.

Disintegration of the social values of Islam

Concept of the caliphate
Most of the difficulties in the time of Uthman arose because of differences about the concept of the Caliphs. Most of the people regarded the Caliph as an Arab Sheikh on a higher scale amenable to the will of the people and even their idiocynracies. Uthman was of the view that the analogy of a tribal Sheikh did not apply to the Caliph.- He held that there was a divinity about the office of the Caliph, which had to be understood with reference to the Quran and the traditions and not in accordance with any man made concepts.

The Holy Quran and the caliphate In the Holy Quran, the term "caliphate" has been used in general terms with reference to communities or people in their collectivity. The word "Caliph" with reference to an individual has been used only once in the Holy Quran with reference to David. Here the word "Caliph" has been used with reference to a ruler or a vicegerent.

There are however numerous traditions on the point. The Holy Prophet said:

"Whoso obeys me obeys God, and whoso rebels against me rebels against God. Whoso obeys the ruler obeys me and whoso rebels against the ruler rebels against me."

The Holy Prophet said:

"After me will come rulers; tender them your obedience for the ruler is like a shield wherewith a man protects himself; if they are righteous and rule you well, they shall have their reward, but if they do evil then punishment will fall upon them, and you will be quit of it, for they are responsible for you, and you have no responsibility."

The Holy Prophet said:

In view of these traditions the view of Uthman was that there was a divinity about the office of the Caliph, and as such the Caliph was responsible to God and not to the people. As such the people had no right to disobey or criticize the Caliph. If the Caliph was just his reward lay with God.

Early Life
'Amr b Al 'Aas belonged to the Sahm section of the Quraish. When the Holy Prophet declared his mission, 'Amr was one of the great opponents of Islam. He even planned the murder of the Holy Prophet. When some of the Muslims migrated to Abyssinia, the Quraish sent a delegation to Abyssinia to prevail upon the Negus to expel the Muslims from his State. 'Amr was one of the members of this delegation. 'Amr was an active member of the delegation, but the delegation failed in its object. At the battle of Uhud, 'Amr commanded the Quraish cavalry.

Conversion to Islam

In his testament, Umar had instructed his successor not to make any change in the administrative set up for one year after his death. True to these instructions, Uthman maintained the status quo in the administrative set up of Egypt.

'Amr b Al 'Aas smarted under the loss of power, and felt dissatisfied at the partition of the province. Soon after the death of Umar, 'Amr b Al 'Aas came to Madina, and apprised Uthman of the state of affairs in Egypt. He pointed out that Egypt was a unity, and its division into two provinces was undesirable politically as well as economically. He pressed Uthman to rescind the orders of partition, depose Abdullah b Sa'ad, and make him ('Amr) the Governor of United Egypt once again.

Early in 646 C.E. a large Byzantine force landed at Alexandria and occupied it. From the base at Alexandria, the Byzantines planned to reconquer the whole of Egypt. The Muslims of Egypt sent a delegation to Madina to prevail on Uthman to restore 'Amr b Al 'Aas and appealed to him to take over the command of Egypt. He stipulated some terms which were accepted by Uthman. 'Amr b Al 'Aas was made the Governor of United Egypt, and he was also to be the supreme commander of the military forces in Egypt. Abdullah b Sa'ad was to hold a subordinate position under 'Amr b Al 'Aas .
