(the wife of the Prophet) Allah's Messenger (ﷺ) died while Abu Bakr was at a place called As-Sunah (Al-'Aliya) 'Umar stood up and said, "By Allah! Allah's Messenger (ﷺ) is not dead!" 'Umar (later on) said, "By Allah! Nothing occurred to my mind except that." He said, "Verily! Allah will resurrect him and he will cut the hands and legs of some men." Then Abu Bakr came and uncovered the face of Allah's Messenger (ﷺ), kissed him and said, "Let my mother and father be sacrificed for you, (O Allah's Messenger (ﷺ)), you are good in life and in death. By Allah in Whose Hands my life is, Allah will never make you taste death twice." Then he went out and said, "O oath-taker! Don't be hasty." When Abu Bakr spoke, 'Umar sat down. Abu Bakr praised and glorified Allah and said, No doubt! Whoever worshipped Muhammad, then Muhammad is dead, but whoever worshipped Allah, then Allah is Alive and shall never die." Then he recited Allah's Statement.:-- "(O Muhammad) Verily you will die, and they also will die." (39.30) He also recited:-- "Muhammad is no more than an Apostle; and indeed many Apostles have passed away, before him, If he dies Or is killed, will you then Turn back on your heels? And he who turns back On his heels, not the least Harm will he do to Allah And Allah will give reward to those Who are grateful." (3.144) The people wept loudly, and the Ansar were assembled with Sad bin 'Ubada in the shed of Bani Saida. They said (to the emigrants). "There should be one 'Amir from us and one from you." Then Abu Bakr, Umar bin Al-Khattab and Abu 'baida bin Al-Jarrah went to them. 'Umar wanted to speak but Abu Bakr stopped him. 'Umar later on used to say, "By Allah, I intended only to say something that appealed to me and I was afraid that Abu Bakr would not speak so well. Then Abu Bakr spoke and his speech was very eloquent. He said in his statement, "We are the rulers and you (Ansars) are the ministers (i.e. advisers)," Hubab bin Al-Mundhir said, "No, by Allah we won't accept this. But there must be a ruler from us and a ruler from you." Abu Bakr said, "No, we will be the rulers and you will be the ministers, for they (i.e. Quarish) are the best family amongst the 'Arabs and of best origin. So you should elect either 'Umar or Abu 'Ubaida bin Al-Jarrah as your ruler." 'Umar said (to Abu Bakr), "No but we elect you, for you are our chief and the best amongst us and the most beloved of all of us to Allah's Messenger (ﷺ)." So 'Umar took Abu Bakr's hand and gave the pledge of allegiance and the people too gave the pledge of allegiance to Abu Bakr. Someone said, "You have killed Sad bin Ubada." 'Umar said, "Allah has killed him."
Sahih al-Bukhari Book 62, Hadith 19
Malik related to me from Hilal ibn Usama from Ata ibn Yasar that
Umar ibn al-Hakam said, "I went to the Messenger of Allah, may Allah
bless him and grant him peace, and said, 'Messenger of Allah, a slave
girl of mine was tending my sheep. I came to her and one of the sheep
was lost. I asked her about it and she said that a wolf had eaten it,
so I became angry and I am one of the children of Adam, so I struck
her on the face. As it happens, I have to set a slave free, shall I
free her?' The Messenger of Allah, may Allah bless him and grant him
peace, questioned her, 'Where is Allah?' She said, 'In heaven.' He
said, 'Who am I?' She said, 'You are the Messenger of Allah.' The
Messenger of Allah, may Allah bless him and grant him peace, said,
'Free her.' "
Muwatta Malik Book 38, Hadith 9
These were the battles of Allah's Messenger (ﷺ) (which he fought), and while mentioning (the Badr battle) he
said, "While the corpses of the pagans were being thrown into the well, Allah's Messenger (ﷺ) said (to them),
'Have you found what your Lord promised true?" `Abdullah said, "Some of the Prophet's companions
said, "O Allah's Messenger (ﷺ)! You are addressing dead people.' Allah's Messenger (ﷺ) replied, 'You do not hear
what I am saying, better than they.' The total number of Muslim fighters from Quraish who fought in
the battle of Badr and were given their share of the booty, were 81 men." Az-Zubair said, "When their
shares were distributed, their number was 101 men. But Allah knows it better."
Sahih al-Bukhari Book 64, Hadith 75
Ghalib quoted a man who stated on the authority of his father that his grandfather reported: They lived at one of the springs. When Islam reached them, the master of the spring offered his people one hundred camels if they embraced Islam. So they embraced Islam, and he distributed the camels among them. But it occurred to him that he should take the camels back from them.
He sent his son to the Prophet (ﷺ) and said to him: Go to the Prophet (ﷺ) and tell him: My father extends his greetings to you. He asked his people to give them one hundred camels if they embraced Islam, and they embraced Islam. He divided the camels among them. But it occurred to him then that he should withdraw his camels from them. Is he more entitled to them or we? If he says: Yes or no, then tell him: My father is an old man, and he is the chief of the people living at the water. He has requested you to make me chief after him.
He came to him and said: My father has extended his greetings to you. He replied: On you and you father be peace. He said: My father asked his people to give them one hundred camels if they embraced Islam. So they embraced Islam, and their belief in Islam is good. Then it occurred to him that he should take his camels back from them. Is he more entitled to them or are they?
He said: If he likes to give them the camels, he may give them; and if he likes to take them back, he is more entitled to them than his people. If they embraced Islam, then for them is their Islam. If they do not embrace Islam, they will be fought against in the cause of Islam.
He said: My father is an old man; he is the chief of the people living at the spring. He has asked you to appoint me chief after him.
He replied: The office of a chief is necessary, for people must have chiefs, but the chiefs will go to Hell.
Sunan Abi Dawud Book 20, Hadith 7
We fought In the company of the Messenger of Allah (ﷺ) with the tribe of Juhaina. They fought with us terribly. When we had finished the noon prayer, the polytheists said: Had we attacked them at once. we would have killed them. Gabriel informed the Messenger of Allah (ﷺ) about It (about their evil design). The Messenger of Allah (ﷺ) made a mention of it to us, adding that they (the polytheists) had also said: Shortly there would be time for the 'Asr prayer. which is dearer o them (the Muslims) than even their children. So when the time of the 'Asr prayer came. we formed ourselves into two rows, while the polytheists were between us and the Qibla. The Messenger of Allah (ﷺ) said: Allah is Most Great, and we also said so. He bowed and we also bowed. He went down in prostration and the first row prostrated along with him. When they stood up, the second row went down in prostration. Then the first row went into the rear, and the second row came in the front and occupied the place of the first row. The Messenger of Allah (ﷺ) then said: Allah is Most Great, and we also said so. He then bowed, and we also bowed. He then went down in prostration and along with him the row also (went down in prostration), and the second row remained standing. And when the second row had also prostrated and all of them sat down then the Messenger of Allah (ﷺ) pronounced salutation to them. Abu Zubair said: Jabir made a mention specially of this thing: just as your chiefs observe prayer.
