Abu Bakr As-Siddiq after Death of Muhammad SAW. A short time after returning from the farewell pilgrimage, Muhammad became ill. In his fatal illness, Muhammad came out with a piece of cloth tied around his head and sat on the pulpit. After thanking and praising Allah he said,ﺇ ﻥ ﺍ ﷲ ﺧﻴﺮ ﻋﺒﺪﺍ ﺑﻴﻦ ﺍﻟﺪ ﻧﻴﺎ ﻭ ﺑﻴﻦ ﻣﺎ ﻋﻨﺪ ﻩ ﻓﺎ ﺧﺘﺎ ﺭ ﺫ ﻟﻚ ﺍﻟﻌﺒﺪ ﻣﺎ ﻋﻨﺪ ﺍﷲ "Allah has given one of His Slaves the choice of receiving the splendor and luxury of the worldly life whatever he likes or to accept the good which is with Allah. So he has chosen that good which is with Allah."
Abu Bakr wept profusely and said, "Our fathers and mothers be sacrificed for you." The companions were astonished by this (they wondered why Abu Bakr wept), and the people said, "Look at this old man! Allah's Apostle talks about a Slave of Allah to whom He has given the option to choose either the splendor of this worldly life or the good which is with Him, while he says "our fathers and mothers be sacrificed for you". It turned out Muhammad himself was that servant, as Abu Bakr later told the companions.
No doubt, I am indebted to Abu Bakr more than to anybody else regarding both his companionship and his wealth. And if I had to take a Khalil from my followers, I would certainly have taken Abu Bakr, but the fraternity of Islam is sufficient. Let no Door of the Mosque remain open, except the door of Abu Bakr.
The good referred in the first part means the good in the hereafter. Khalil means intimate friend. The door referred to here is the door to the mosque of Muhammad. When the fever developed he directed Abu Bakr to go to the war following Usama who was 18. When Muhammad died Muslims gathered in Al-Masjid al-Nabawi and there were suppressed sobs and sighs. Abu Bakr came from his house at As-Sunh (a village) on a horse where he had been with his new wife. He dismounted and entered the Prophet's Mosque, but did not speak to anyone until he entered upon 'Aa'isha. He went straight to Muhammad who was covered with Hibra cloth (a kind of Yemenite cloth). He then uncovered Muhammad's face and bowed over him and kissed him and wept, saying, "Let my father and mother be sacrificed for you. By Allah, Allah will never cause you to die twice. As for the death which was written for you, has come upon you." 'Umar was making a sermon to the people saying, "By Allah, he is not dead but has gone to his Lord as Musa ibn Imran went and remained hidden from his people for forty days. Musa returned after it was said that he had died. By Allah, the Messenger of Allah will come back and he will cut off the hands and legs of those who claim his death."
Abu Bakr arrived and said, "Sit down, O 'Umar!" But 'Umar refused to sit down. So the people came to Abu Bakr and left Umar. Abu Bakr said, "To proceed, if anyone amongst you used to worship Muhammad, then Muhammad has passed away, but if (anyone of) you used to worship Allah, then Allah is Alive and shall never die. Allah said, "And Muhammad is but a messenger; the messengers have come before him; if then he dies or is killed will you turn back upon your heels? And whoever turns back upon his heels, he will by no means do harm to Allah in the least and Allah will reward the grateful." (3.144)
'Umar said, "By Allah, when I heard Abu Bakr reciting it, my legs could not support me and I fell down at the very moment of hearing him reciting it, declaring that the Prophet had passed away."
