Narrated It was narrated that Ibn al Musayyab said:
When Abu Bakr died, people wept for him. `Umar said: The Messenger of Allah (ﷺ) said: `The deceased is tormented because of the weeping of the living.”
Narrated It was narrated from Malik bin Aws that al-Hadathan said:
‘Umar sent word to me... and he mentioned the hadeeth. I said to you both]: The Messenger of Allah (ﷺ) said: `We are not to be inherited from and what we leave behind is charity.`
When the Messenger of Allah (ﷺ) died and some people apostatised, ‘Umar bin al-Khattab said: O Abu Bakr, how can you fight the people, when the Messenger of Allah (ﷺ) said: “I have been commanded to fight the people until they say La ilaha illallah (There is no god but Allah), and whoever says La ilaha illallah, his wealth and his life are protected from me, and his reckoning will be with Allah`? Abu Bakr said: I will most certainly fight those who separate prayer and zakah, for zakah is what is due on wealth. By Allah, if they withhold from me a small she-goat that they used to give to the Messenger of Allah (ﷺ), I will certainly fight them for withholding it. ʻUmar said: By Allah, as soon as I saw that Allah had opened Abu Bakr`s heart to the idea of fighting I knew that he was right.
Narrated It was narrated from Salim from Ibn ‘Umar that he said to `Umar:
I heard the people saying something so I decided that I should talk to you. They are saying that you are not going to appoint a successor. He lowered his head for a while, then he looked up and said: Allah, may He be glorified and exalted, will protect His religion. If I do not appoint a successor, the Messenger of Allah (ﷺ) did not appoint a successor either; if I do appoint a successor, Abu Bakr appointed a successor. By Allah, once he mentioned the Messenger of Allah (ﷺ) and Abu Bakr, I realized that he was not going to regard anyone else as equal to the Messenger of Allah (ﷺ) and that he was not going to appoint a successor.
