Jami` at-Tirmidhi Book 49, Hadith 85
"The Messenger of Allah (ﷺ) awoke in the morning and called for Bilal, then said: 'O Bilal! By what have you preceded me to Paradise? I have not entered Paradise at all, except that I heard your footsteps before me. I entered Paradise last night, and I heard your footsteps before me, and I came upon a square palace having balconies made of gold. So I said: 'Whose palace is this?' They said: 'A man among the Arabs.' So I said: 'I am an Arab, whose palace is this?' They said: 'A man among the Quraish.' So I said: 'I am from the Quraish, whose palace is this?' They said: 'A man from the Ummah of Muhammad (ﷺ).' So I said: 'I am Muhammad, whose palace is this?' They said: ''Umar bin Al-Khattab's.' So Bilal said: 'O Allah's Messenger! I have never called the Adhan except that I prayed two Rak'ah, and I never committed Hadath except that I performed Wudu upon that, and I considered that I owed Allah two Rak'ah.' So the Messenger of Allah (ﷺ) said: 'For those two.'"
that the Prophet (ﷺ) said: "I entered Paradise and it was as if I was in a palace of gold. So I said: 'Whose palace is this?' They said: 'A youth's, from the Quraish.' So I thought that I was him. I said: 'And who is he?' They said: "'Umar bin Al-Khattab."
"The Messenger of Allah (ﷺ) went out for one of his expeditions, then when he came back, a black slave girl came to him and said: 'O Messenger of Allah! I took an oath that if Allah returned you safely, I would beat the Duff before you and sing.' So the Messenger of Allah (ﷺ) said to her: 'If you have taken an oath, then beat it, and if you have not then do not.' So she started to beat the Duff, and Abu Bakr entered while she was beating it. Then 'Ali entered while she was beating it, then 'Uthman entered while she was beating it. Then 'Umar entered, so she put the Duff under her, and sat upon it. So the Messenger of Allah (ﷺ) said: 'Indeed Ash-Shaitan is afraid of you O 'Umar! I was sitting while she beat it, and then Abu Bakr entered while she was beating it, then 'Ali entered while she was beating it, then 'Uthman entered while she was beating it, then when you entered O 'Umar and she put away the Duff.'
