Hadith Narrated By Thabit that Anas

"Salman felt sick and Sad came to visit him, and when he saw him he wept. Sad said to him: Why are you weeping, my brother? Are you not a Companion of the Messenger of Allah (saw)? Are you not? Are you not? Salman said: I am only weeping for one reason: I am not weeping because of longing for this world or for dislike of the Hereafter. But the Messenger of Allah (saw) gave me some advice and I think that I have transgressed. He said: What was his advice to you? He said: He advised me that something like the provision of a rider is sufficient for anyone of you, and I think that I have transgressed that. As for you, O Sad, fear Allah when you pass a verdict, and when you distribute (spoils of war), and when you decide to do anything."
