When Allah's Messenger (ﷺ) became seriously ill, Bilal came to him for the prayer. He said, "Tell Abu Bakr
to lead the people in the prayer." I said, "O Allah's Messenger (ﷺ)! Abu Bakr is a softhearted man and if he
stands in your place, he would not be able to make the people hear him. Will you order `Umar (to lead
the prayer)?" The Prophet (ﷺ) said, "Tell Abu Bakr to lead the people in the prayer." Then I said to Hafsa,
"Tell him, Abu i Bakr is a softhearted man and if he stands in his place, he would not be able to make
the people hear him. Would you order `Umar to lead the prayer?' " Hafsa did so. The Prophet (ﷺ) said,
"Verily you are the companions of Joseph. Tell Abu Bakr to lead the people in the prayer." So Abu-
Bakr stood for the prayer. In the meantime Allah's Messenger (ﷺ) felt better and came out with the help of
two persons and both of his legs were dragging on the ground till he entered the mosque. When Abu
Bakr heard him coming, he tried to retreat but Allah's Messenger (ﷺ) beckoned him to carry on. The Prophet (ﷺ)
sat on his left side. Abu Bakr was praying while standing and Allah's Messenger (ﷺ) was leading the prayer
while sitting. Abu Bakr was following the Prophet (ﷺ) and the people were following Abu Bakr (in the
prayer).
Sahih al-Bukhari Book 10, Hadith 108
Jabir bin `Abdullah said, "When the Prophet (ﷺ) died, Abu Bakr received some property from Al-`Ala bin
Al-Hadrami. Abu Bakr said to the people, "Whoever has a money claim on the Prophet, or was
promised something by him, should come to us (so that we may pay him his right)." Jabir added, "I
said (to Abu Bakr), Allah's Messenger (ﷺ) promised me that he would give me this much, and this much, and
this much (spreading his hands three times)." Jabir added, "Abu Bakr counted for me and handed me
five-hundred (gold pieces), and then five-hundred, and then five-hundred."
Sahih al-Bukhari Book 52, Hadith 44
Pray with us these two, meaning two days. When the sun passed the meridian, he gave command to Bilal who uttered the call to prayer. Then he commanded him and pronounced Iqama for noon prayer (Then at the time of the afternoon prayer) he again commanded and Iqama for the afternoon prayer was pronounced when the sun was high, white and clear. He then commanded and Iqama for the evening prayer was pronounced, when the sun had set. He then commanded him and the Iqama for the night prayer was pronounced when the twilight had disappeared. He then commanded him and the Iqama for the morning prayer was pronounced, when the dawn had appeared. When it was the next day, he commanded him to delay the noon prayer till the extreme heat had passed and he did so, and he allowed it to be delayed till the extreme heat had passed. He observed the afternoon prayer when the sun was high, delaying it beyond the time he had previously observed it. He observed the evening prayer before the twilight had vanished; he observed the night prayer when a third of the night had passed; and he observed the dawn prayer when there was clear daylight. He (the Holy Prophet) then said: Where is the man who inquired about the time of prayer? He (the inquirer) said: Messenger of Allah, here I am. He (the Holy Prophet) said: The time for your prayer is within the limits of what you have seen.
Sahih Muslim Book 5, Hadith 225
"The people of As-Suffah were the guests of the people of Islam,they had nothing of people nor wealth to rely upon. And By Allah, the One Whom there is none worthy of worship besides Him – I would lay on the ground on my liver (side) due to hunger, And I would fasten a stone to my stomach out of hunger. One day I sat by the way that they (the Companions) use to come out through. Abu Bakr passed and so I asked him about an Ayah from Allah's Book, not asking him except that he might tell me to follow him (for something to eat). But he passed on without doing so. Then `Umar passed, so I asked him about an Ayah from Allah's Book, not asking him except that he might tell me to follow him. But he passed on without doing so. Then Abul-Qasim (s.a.w) passed, and he smiled when he saw me, and said: 'Abu Hurairah?' I said: 'I am here O Messenger of Allah!' He said: 'Come along.' He continued and I followed him, he entered his house, so I sought permission to enter, and he permitted me. He found a bowl of milk and said: 'Where did this milk come from?' It was said: 'It was a gift to us from so – and – so.' So the Messenger of Allah (s.a.w) said: 'O Abu Hurairah' I said: 'I am here O Messenger of Allah!' He said: 'Go to the people of As-Suffah to invite them.' - Now, they were the guests of the people of Islam, they had nothing of people nor wealth to rely upon. Whenever some charity was brought to him, he would send it to them without using any of it. And when a gift was given to him (s.a.w), he would send for them to participate and share with him in it. I became upset about that, and I said (to myself): 'What good will this bowl be among the people of As-Suffah and I am the one bringing it to them?' Then he ordered me to circulate it among them (So I wondered) what of it would reach me from it, and I hoped that I would get from it what would satisfy me. But I would certainly not neglect to obey Allah and obey His Messenger, so I went to them and invited them. When they entered upon him they sat down. He said: 'Abu Hurairah, take the bowl and give it to them.' So I gave it to a man who drank his fill, then he gave it to another one, until it ended up with the Messenger of Allah (s.a.w), and all of the people had drank their fill. The Messenger of Allah (s.a.w) took the bowl, put it on his hand,then raised his head. He smiled and said: 'Abu Hurairah, drink.' So I drank, then he said: 'Drink.' I kept drinking and he kept on saying, 'Drink.' Then I said: 'By the One Who sent you with the truth! I have no more space for it.' So he took the bowl and praised Allah, mentioned His Name and drank.'” (Sahih)
