Open it for him and give him glad tidings of Paradise and, lo, it was Abu Bakr. I opened (the gate) for him and gave him the glad tidings of Paradise. Then another person asked for the door to be opened, whereupon he said: Open it and give him the glad tidings of Piradise. He said: I went away and, lo, it was 'Umar. I opened it for him and gave him the glad tidings of Paradise. Then still another man asked for the door to be opened, and thereupon Allah's Apostle (may peace be upon him) said: Open it and give him the glad tidings of Paradise after a trial would afflict him. I went and, lo, it was 'Uthman b. 'Affan. 1 opened the door and gave him the glad tidings of Paradise and informed him (what the Holy Prophet had said).

Yahya related to me from Malik from Yahya ibn Said from Muhammad ibn Ibrahim that Abd ar-Rahman ibn Abi Amra al-Ansari said that Uthman ibn Affan came to the isha prayer and seeing only a few people in the mosque, he lay down at the back of the mosque to wait for the number of people to increase. Ibn Abi Amra went and sat down beside him and Uthman asked him who he was, so he told him. Uthman said, "What have you memorised of the Qur'an?", and he told him. Uthman said, "If someone is present at isha, it is as if he had stood in prayer for half a night, and if some one is present at subh, it is as if he had stood in prayer for a whole night.

Yahya related to me from Malik, from Nafi, from Nubayh ibn Wahb, who was from the tribe of Bani Abd ad-Dar, that Umar ibn Ubaydullah sent a message to Aban ibn Uthman (who was amir of the hajj at the time), while both of them were in ihram, saying, "I want to marry Bint Shayba ibn Jubayr to Talha ibn Umar and I want you to be present." Aban told him that he should not do that and said, "I heard Uthman ibn Affan say that the Messenger of Allah, may Allah bless him and grant him peace, said, 'A man in ihram should not marry, or give in marriage, or get betrothed.' "

from 'Uthman bin 'Affan that the Messenger of Allah (SAW) said: "The best of you is he who learns the Qur'an and teaches it." Abu 'Abdur-Rahman said: "So that is why I sit at this seat of mine." And he taught the Qur'an during the time of 'Uthman until Al-Hajjaj bin Yusuf came. (Sahih)

Are you going to give up what I heard about you? He was apologetic, then `Uthman (رضي الله عنه) said: Woe to you! I heard and remembered and it is not as you heard; the Messenger of Allah (ﷺ) said: `A leader will be killed and a criminal will commit a crime.` I am the one who will be killed, not ‘Umar رضي الله عنه); rather ‘Umar (رضي الله عنه) was killed by one man, but a group of people will kill me

"I used to sell dates in the marketplace, and I would say: 'This was such and such an amount (when I bought it).' I Would give the purchaser a specific amount of dates according to the way it had been measured for me, and take my profit.

Umar bin Ubaidullah bin Ma'mar was complaining about his eyes while he was a Muhrim. He asked Aban bin Uthman about it and he said: "Bandage it with some aloes, for I heard Uthman bin Affan mentioning that the Messenger of Allah said: 'Bandage it with aloes.'"

Husain bin Abi Waqqas said: l heard `Uthman bin `Affan (رضي الله عنه) say: What prevented me from narrating from the Messenger of Allah (ﷺ) was not the fact that was not the most knowledgeable of his Companions about what he said, but I bear witness that I heard him say: “Whoever says something about me that I did not say, let him take his place in Hell.” And he said: Husain was the most aware of his companions of what he said.

The Messenger of Allah (ﷺ) said: `There is no Muslim who leaves his house, intending to travel or otherwise, and says when leaving: `In the Name of Allah, I believe in Allah, I seek the protection of Allah, I put my trust in Allah, there is no strength and no power except with Allah, but he will be granted the goodness of that going out, and the evil of that going out will be diverted from him.”
