When Allah's Messenger (ﷺ) 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 Messenger (ﷺ)
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 Messenger (ﷺ), 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."
Sahih al-Bukhari Book 96, Hadith 16
Allah's Messenger (ﷺ) came out as the sun declined at midday and offered the Zuhr prayer. He then stood on
the pulpit and spoke about the Hour (Day of Judgment) and said that in it there would be tremendous
things. He then said, "Whoever likes to ask me about anything he can do so and I shall reply as long as
I am at this place of mine. Most of the people wept and the Prophet (ﷺ) said repeatedly, "Ask me."
`Abdullah bin Hudhafa As-Sahmi stood up and said, "Who is my father?" The Prophet (ﷺ) said, "Your
father is Hudhafa." The Prophet (ﷺ) repeatedly said, "Ask me." Then `Umar knelt before him and said,
"We are pleased with Allah as our Lord, Islam as our religion, and Muhammad as our Prophet." The
Prophet then became quiet and said, "Paradise and Hell-fire were displayed in front of me on this wall
just now and I have never seen a better thing (than the former) and a worse thing (than the latter).
Sahih al-Bukhari Book 9, Hadith 17
I was ten years old when Allah's Messenger (ﷺ) arrived at Medina. My mother and aunts used to urge me to
serve the Prophet (ﷺ) regularly, and I served him for ten years. When the Prophet (ﷺ) died I was twenty years
old, and I knew about the order of Al-Hijab (veiling of ladies) more than any other person when it was
revealed. It was revealed for the first time when Allah's Messenger (ﷺ) had consummated his marriage with
Zainab bint Jahsh. When the day dawned, the Prophet (ﷺ) was a bridegroom and he invited the people to a
banquet, so they came, ate, and then all left except a few who remained with the Prophet (ﷺ) for a long
time. The Prophet (ﷺ) got up and went out, and I too went out with him so that those people might leave
too. The Prophet (ﷺ) proceeded and so did I, till he came to the threshold of `Aisha's dwelling place. Then
thinking that these people have left by then, he returned and so did I along with him till he entered
upon Zainab and behold, they were still sitting and had not gone. So the Prophet (ﷺ) again went away and
I went away along with him. When we reached the threshold of `Aisha's dwelling place, he thought
that they had left, and so he returned and I too, returned along with him and found those people had
left. Then the Prophet (ﷺ) drew a curtain between me and him, and the Verses of Al-Hijab were revealed.
