Mu'tamir narrated to us, he says: I narrated to my father the hadith of Abu 'Uthman, who narrates from Salman, that he said: Those who do good in this world are the ones deserving of good treatment in the Hereafter. So he said: I heard this from Abu 'Uthman, and he used to narrate from Salman, so I realized that this is the same, and I have never narrated this hadith to anyone. And in another narration: It is narrated from Abu 'Uthman that the Messenger of Allah ( صلی اللہ علیہ وسلم ) used to say the same as Mu'tamir has narrated.
