"The Messenger of Allah (ﷺ) said to me: 'If you want to stick with me, then suffice yourself in the world with the provisions of the rider. And beware of gatherings of the rich, and do not consider a garment to be worn out until it has been patched.'"

This Hadith is Gharib, we do not know of it except as a narration of Salih bin Hassan. He said: I heard Muhammad bin Isma'il saying: "Salih bin Hassan is Munkar is Hadith." And Salih bin Hassan - the one who Ibn Abi Dhi'b reports from - is trustworthy.

And it has been related from 'Awn bin 'Abdullah who said: "I accompanied the rich, and did not see anyone with more troubles than me. I saw a beast that was better than my beast, and a garment that was better than my garment. And I accompanied the poor, and felt at ease."
