Start of Islamic era A kind of government in the Islamic world at lasted for almost 13 century from the death of hazrat Muhammad (?) to the over through of the last ottoman caliph Abd al-Madjeed al-Thâni in 1924. Through the one and half decease of century the word of caliph turned but has been used at the time curse in June 2014 by an aggressive group considering themselves isls and also announcing the establishment of caliphate and they also proclaimed their leader Abu baker al Baghdadi. On the meanwhile this call rejected by most Muslims around the world.In 622 hazrat Muhammad (?) left his homeland city mecca move toward to the medina with his some best followers by order of Allah. When they reached medina people of medina call them (muhajroon) immigrants. The prophet (?) and the immigrants given the shelter by the citizen of medina after this they (people of media) also known as supporter (al ansar). Hazrat Muhammad (?) laid the foundation of Islamic government in medina. After ten year in 632 he (?) died after a brief illness in medina. The prophet (?) left behind the young and vibrate Islamic government which uniting most of the tribe of the Arabian peninsula with medina its capital. It was censorious condition because prophet had both spiritual and political authority and it was really difficult for anyone to unite those two qualities. But it was vital that Islam should continue to grow and that’s way a leader was needed. The People of medina and other followers thought the close companion of the prophet (?) is successor would come from one of them. The supporters and their tribe leaders felt that they were the people of city and greater in number and that it was their right to take leadership after prophet (?). The supporter gathered to decide which of them would be the prophet successor because the holy prophet was last prophet and there was to be no prophet after him. He was also leader of Muslims therefore necessary that after him there should be someone who lead the Muslim government and also solving the Muslims affairs chosen from us because we gave them salter and property share when they were alone. Someone told hazrat Abu baker (R.A) about the meeting then Abu baker (R.A) and Umar (R.A) reached at meeting place and interrupted the deliberation. Hazrat Abu baker (R.A) brought the delegation at home and asked it is the no matter of medina city it is the matter of whole Arab and whole world we first accept the Islam and we also left ours houses, parents, and tribe for the separation of Islam and Allah and he also asked supporters about government and other Arab tribe who will not accept the government of (Ansar) supporter and he also added that the scarification of supporter for the Islam will not forget and their value is high then a supporter leader stand and said Abu baker (R.A) is right but he also added that the maximum adjustment that they could make in favor of the emigrants was that they could have two Amirs, one from the supporter (Ansars) and the other from the emigrants,hazrat Umar (R.A) said that Islam give the teaching of unity for one Allah, one Prophet, and one Quran. It followed as a required result that the Muslim community should have one Amir. If the plan of having two Amirs was once accepted, other people would later lay claim to the election of an Amir from them. Such multiple Amirat would lead to the losing the strength of the Islamic polity after the long and hot debate one of leader of supporter arose and said to the supporter you were the first helper of Islam and this time you are the first hurdle in Islamic solidity at this supporter fell in deep thought and they seemed to hesitate to press their demand. Abu baker (R.A) take stage and asked to the delegation will you accept the hazrat Umar (R.A) as a new leader for the government then suddenly hazrat Umar (R.A) I don’t put myself ahead of Abu baker (R.A) and he said you are senior and also lead the prayers during the illness of prophet (?) and you have deserve this succession. Then Abu baker (R.A) said so give me your hand and hazrat Umar (R.A) gave his hand for oath and other people also give the oath to hazrat Abu baker (R.A) in this way that problem came to end.Realm of caliphate The new time began a new title written in history the first caliph of Islam and successor of Muhammad (?) was to be hazrat Abu baker (R.A). In the next the position of Abu baker (R.A) was confirmed as caliph.

He was modest and very spiritual man. During his period many up and downs came which create the many problem for the new Islamic government like Musaylimah and 2nd issue is zakat when many Muslims severed from the zakat. On that time he fought against them during these wars many lives lost by Muslims and Muslims also lost 300 plus hufiz e Qur’an after the this he ordered the Muslims to collect the Qur’an and he also himself a hafiz then he arrange the Qur’an in a book form in his period Qur’an should write and arrange in the form of book.

A time came when the 1000 people sent to medina to kill the caliph, on the daily basis riots increases in medin.The main reason for arose of the anti-Usman movement is disputed between the Shia and Sunni Muslims.
