When Abu Bakr As-Siddiq was chosen Caliph, he said, "My people know that my profession was not incapable of providing substance to my family. And as I will be busy serving the Muslim nation, my family will eat from the National Treasury of Muslims, and I will practice the profession of serving the Muslims."

It was said to `Umar, "Will you appoint your successor?" `Umar said, "If I appoint a Caliph (as my successor) it is true that somebody who was better than I (i.e., Abu Bakr) did so, and if I leave the matter undecided, it is true that somebody who was better than I (i.e., Allah's Apostle) did so." On this, the people praised him. `Umar said, "People are of two kinds: Either one who is keen to take over the Caliphate or one who is afraid of assuming such a responsibility. I wish I could be free from its responsibility in that I would receive neither reward nor retribution I won't bear the burden of the caliphate in my death as I do in my life."

When the Prophet died and Abu Bakr became his successor and some of the Arabs reverted to disbelief, `Umar said, "O Abu Bakr! How can you fight these people although Allah's Apostle said, 'I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah, 'and whoever said, 'None has the right to be worshipped but Allah', Allah will save his property and his life from me, unless (he does something for which he receives legal punishment) justly, and his account will be with Allah?' "Abu Bakr said, "By Allah! I will fight whoever differentiates between prayers and Zakat as Zakat is the right to be taken from property (according to Allah's Orders). By Allah! If they refused to pay me even a kid they used to pay to Allah's Apostle, I would fight with them for withholding it." `Umar said, "By Allah: It was nothing, but I noticed that Allah opened Abu Bakr's chest towards the decision to fight, therefore I realized that his decision was right."

When Allah's Apostle died and Abu Bakr was elected as a Caliph after him, some of the Arabs reverted to disbelief, `Umar said to Abu Bakr, "How dare you fight the people while Allah's Apostle said, I have been ordered to fight the people till they say 'None has the right to be worshipped but Allah' And whoever says: None has the right to be worshipped but Allah.' waves his wealth and his life from me unless he deserves a legal punishment lusty, and his account will be with Allah! Abu Bakr said, "By Allah, I will fight him who discriminates between Zakat and prayers, for Zakat is the Compulsory right to be taken from the wealth By Allah, if they refuse to give me even a tying rope which they use to give to Allah's Apostle, I would fight them for withholding it." `Umar said, 'By Allah, It was nothing, except I saw that Allah had opened the chest of Abu Bakr to the fight, and I came to know for certain that was the truth."

While I was at Yemen, I met two men from Yemen called Dhu Kala and Dhu `Amr, and I started telling them about Allah's Apostle. Dhu `Amr said to me, "If what you are saying about your friend (i.e. the Prophet) is true, then he has died three days ago." Then both of them accompanied me to Medina, and when we had covered some distance on the way to Medina, we saw some riders coming from Medina. We asked them and they said, "Allah's Apostle has died and Abu Bakr has been appointed as the Caliph and the people are in a good state.' Then they said, "Tell your friend (Abu Bakr) that we have come (to visit him), and if Allah will, we will come again." So they both returned to Yemen. When I told Abu Bakr their statement, he said to me, "I wish you had brought them (to me)." Afterwards I met Dhu `Amr, and he said to me, "O Jarir! You have done a favor to me and I am going to tell you something, i.e. you, the nation of 'Arabs, will remain prosperous as long as you choose and appoint another chief whenever a former one is dead. But if authority is obtained by the power of the sword, then the rulers will become kings who will get angry, as kings get angry, and will be delighted as kings get delighted."

That the Prophet said, "No Caliph is appointed but has two groups of advisors: One group advises him to do good and urges him to adopt it, and the other group advises him to do bad and urges him to adopt it; and the protected is the one whom Allah protects."

Allah's Apostle set out for Tabuk. appointing `Ali as his deputy (in Medina). `Ali said, "Do you want to leave me with the children and women?" The Prophet said, "Will you not be pleased that you will be to me like Aaron to Moses? But there will be no prophet after me."
