Narrated Sa`eed bin al-Musayyab said. I heard ‘Uthman (رضي الله عنه) delivering a khutbah from the minbar. He said:
I used to buy dates from one of the Jewish clans who were called Banu Qainuqa`, and sell them at a profit. News of that reached the Messenger of Allah (ﷺ) who said: `O `Uthman, when you buy, take your dues with nothing extra, and when you sell, give (the other party`s) dues with nothing less.`
Moosa bin Wardan narrated from Sa`eed bin al-Musayyab from ‘Uthman bin `Affan (رضي الله عنه)... and he mentioned a similar report.
Narrated `Abdullah bin ‘AbdurRahman bin Abi Dhubab narrated from his father that ‘Uthman bin ‘Affan (رضي الله عنه) prayed four rak`ahs in Mina and the people objected to that. He said:
O people, I have taken a wife in Makkah since I came here, and I heard the Messenger of Allah (ﷺ)say: “Whoever takes a wife in a city should offer the prayer of one who is a resident (i.e., in full).
Narrated It was narrated from Aban bin `Uthman that his father said:
The Messenger of Allah (ﷺ) said: `Whoever says in the Name of Allah, with whose name nothing on earth or in heaven can cause harm, and He is the All-Hearing, All-Knowing, nothing will harm him.`
Narrated it was narrated that Abu Salih, the freed slave of `Uthman, said:
I heard `Uthman in Mina saying: O people, I shall tell you a hadeeth that I heard from the Messenger of Allah (ﷺ) . He said: `Standing guard on the border for one day for the sake of Allah is better than one thousand ordinary days, so let a man stand on guard at the border as much as he wants.” ? They said: Yes. He said: O Allah, bear witness.
