Sahih al-Bukhari Book 34, Hadith 54
Allah's Messenger (ﷺ) said, "The example of a good companion (who sits with you) in comparison with a
bad one, is like that of the musk seller and the blacksmith's bellows (or furnace); from the first you
would either buy musk or enjoy its good smell while the bellows would either burn your clothes or
your house, or you get a bad nasty smell thereof."
We set out with Allah's Messenger (ﷺ) in the year of Hunain, (the Prophet (ﷺ) gave me an armor). I sold that armor and bought a garden in the region of the tribe of Bani Salama and that was the first property I got after embracing Islam.
Abu Taiba cupped Allah's Messenger (ﷺ) so he ordered that he be paid one Sa of dates and ordered his masters to reduce his tax (as he was a slave and had to pay a tax to them).
