سنن ابن ماجه

It was narrated from Thabit that Anas said: “Salman felt sick and Sa’d came to visit him, and when he saw him he wept. Sa’d said to him: ‘Why are you weeping, my brother? Are you not a Companion of the Messenger of Allah (ﷺ)? 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 (ﷺ) 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 Sa’d, fear Allah when you pass a verdict, and when you distribute (spoils of war), and when you decide to do anything.’”
