In about 650, Uthman began noticing slight differences in recitations of the
Quran as Islam expanded beyond the
Arabian Peninsula into
Persia, the
Levant, and
North Africa. In order to preserve the sanctity of the text, he ordered a committee headed by
Zayd ibn Thabit to use caliph
Abu Bakr's copy and prepare a standardised version of the Quran. Thus, within 20 years of Muhammad's death, the Quran was committed to written form. That text became the model from which copies were made and promulgated throughout the urban centers of the Muslim world, with the other versions ordered to be burnt by Uthman. While the Shī'ah use the same
Qur'an as Sunni Muslims, they do not believe that it was first compiled by Uthman. Rather, the Shī'ah believe that the Qur'an was gathered and compiled by
Muhammad during his lifetime.

allowance and, on assuming office, Uthman increased it by about 25%. Umar had placed a ban on the sale of lands and the purchase of
agricultural lands in conquered territories. Uthman withdrew these restrictions, as the trade could not flourish. Uthman also permitted people to draw loans from the public treasury. Under Umar, it had been laid down as a policy that the lands in conquered territories were not to be distributed among the combatants but were to remain the property of the previous owners. The army felt dissatisfied at this decision, but Umar suppressed the opposition with a strong hand. Uthman followed the policy devised by Umar and there were more conquests, and the revenues from land increased considerably. The conquest of Armenia had begun by the 640s.
Mu'awiya had been appointed the governor of Syria by
Umar in 639 to stop Byzantine harassment from the sea during the
Arab-Byzantine Wars. He succeeded his elder brother
Yazid ibn Abi Sufyan, who died in a plague, along with
Abu Ubayda ibn al-Jarrah, the governor before him, and 25,000 other people. Now under Uthman's rule in 649, Mu'awiya was allowed to set up a navy, manned by
Monophysitic Christians,
Copts, and
Jacobite Syrian Christian sailors and Muslim troops, which defeated the Byzantine navy at the
Battle of the Masts in 655, opening up the Mediterranean. In
Hijri year 15 (), Uthman sent
Abd Allah ibn al-Zubayr and
Abd Allah ibn Sa'd to
reconquer the Maghreb, where he met the army of
Gregory the Patrician,
Exarch of Africa and relative of
Heraclius, which is recorded to have numbered between 120,000 and 200,000 soldiers, The opposing forces clashed at Sabuthilag (or
Sufetula), which became the name of this battle. Records from
al-Bidayah wal Nihayah state that Ibn Sa'd's troops were completely surrounded by Gregory's army. However, Abd Allah ibn al-Zubayr spotted Gregory in his chariot and asked Abd Allah ibn Sa'd to lead a small detachment to intercept him. The interception was successful, and Gregory was slain by Ibn al-Zubayr's ambush party. Consequently, the morale of Byzantine army started crumbling and soon they were routed.) claimed that after the conquest of northern Africa was completed, Abd Allah ibn Sa'd continued to Spain. Other prominent Muslim historians, like
Ibn Kathir, have quoted the same narration. In the description of this campaign, two of Abd Allah ibn Sa 'd's generals, Abdullah ibn Nafiah ibn Husain and Abdullah ibn Nafi ibn Abdul Qais, were ordered to invade the coastal areas of Spain by sea, aided by a Berber force. They allegedly succeeded in conquering the coastal areas of
Al-Andalus. It is not known where the Muslim force landed, what resistance they met, and what parts of Spain they actually conquered. However, it is clear that the Muslims did conquer some portion of Spain during the caliphate of Uthman, presumably establishing colonies on its coast. On this occasion, Uthman is reported to have addressed a letter to the invading force: Although raids by Berbers and Muslims were conducted against the
Visigothic Kingdom in Spain during the late 7th century, there is no evidence that Spain was invaded nor that parts of it were conquered or settled by Muslims prior to the 711 campaign by
Tariq. Abd Allah ibn Sa'd also achieved success in the Caliphate's first decisive naval battle against the
Byzantine Empire, the
Battle of the Masts. To the east,
Ahnaf ibn Qais, chief of
Banu Tamim and a veteran commander who conquered
Shushtar earlier, launched a series of further military expansions by
further mauling Yazdegerd III near
Oxus River in
Turkmenistan and later crushing a military coalition of
Sassanid loyalists and
Hephthalites in the
Siege of Herat. In the next year, in 652,
Futuh al-Buldan of Baladhuri writes that
Balochistan was re-conquered during the campaign against the revolt in Kermān, under the command of Majasha ibn Mas'ud. It was the first time that western Balochistan had come directly under the laws of the Caliphate and it paid an agricultural tribute. The military campaigns under Uthman's rule were generally successful, except for a few in
Nubia, on the lower Nile.
Public opposition to Uthman's policies Reasons for the opposition Noting an increase in anti-government tension around the Caliphate, Uthman's administration decided to determine its origins, extent, and aims. Some time around 654, Uthman called all twelve provincial governors to Medina to discuss the problem. During this Council of Governors, Uthman ordered that all resolutions of the council be adopted according to local circumstances. Later, in the Majlis al Shurah (council of ministers), it was suggested to Uthman that reliable agents be sent to various provinces to attempt to determine the source of the discontent. Uthman accordingly sent
Muhammad ibn Maslamah to
Kufa,
Usama ibn Zayd to
Basra,
Ammar ibn Yasir to Egypt, and
Abd Allah ibn Umar to Syria. The agents sent to Kufa, Basra and Syria reported that all was well – the people were generally satisfied with the administration, although some individuals had minor personal grievances. Ammar ibn Yasir, the emissary to Egypt, however, did not return to Medina. Rebels there had been issuing propaganda in favour of making Ali caliph. Ammar ibn Yasir, who had been affiliated with Ali, abandoned Uthman for the Egyptian opposition. Abd Allah ibn Sa'd, the governor of Egypt, reported about the opposition's activities instead. He wanted to take action against
Muhammad ibn Abi Bakr (Ali's foster son),
Muhammad ibn Abi Hudhayfa (Uthman's adopted son), and Ammar ibn Yasir.
Uthman's attempts to appease the dissidents In 655, Uthman directed those with any grievance against the administration, as well as the governors and "Amils" throughout the caliphate, to assemble at Mecca for the Hajj, promising that all legitimate grievances would be redressed. Accordingly, large delegations from various cities came to present their grievances before the gathering. The rebels realised that the people in Mecca supported Uthman and were not inclined to listen to them. This represented a great psychological victory for Uthman. It is said, according to Sunni Muslim accounts, that before returning to Syria, the governor
Mu'awiya ibn Abi Sufyan, Uthman's cousin, suggested that Uthman should come with him to Syria as the atmosphere there was peaceful. Uthman rejected his offer, saying that he did not want to leave the city of Muhammad (
viz., Medina). Mu'awiya then suggested that he be allowed to send a strong force from Syria to Medina to guard Uthman against any possible attempt by rebels to harm him. Uthman rejected it as well, stating that the presence of Syrian forces in Medina would be an incitement to
civil war, and he could not be party to such a move. == Revolt against Uthman ==
