Salman was suffering from illness, so Sa’d visited him and saw him
crying, so he said to him, “What is it that makes you weep, O my
brother? Did you not accompany the Messenger of Allâh (saw)? Is that not
so, is that not so?!” Salman replied, “I am not weeping for either of
the following reasons: I am not weeping for the sake of the world nor
out of hate of the Hereafter. Rather the Messenger of Allâh (saw)
entrusted me with a pledge, and I can only see myself as
having transgressed.” So he asked, “What were you entrusted
with?” He replied, “He entrusted me with a pledge that the provision
of a traveller should suffice anyone of us, and I see myself as only having
transgressed. And as for you, O Sa’d! Fear Allâh with your ruling when
you make a judgement, and fear Him with your distribution when you
distribute, and fear Him with your intention when you intend to do
something.”" (Ibn Mâjah and others)
