The Seller of Musk (Good Companion) (FULL VID) by Abu Mussab Wajdi Akkari

"The case of the good companion and the bad companion is like that of the seller of musk and the blower of the bellows (iron-smith). As for the seller of musk, he will either give you some of the musk, or you will purchase some from him, or at least you will come away having experienced its good smell. Whereas the blower of the bellows will either burn your clothing, or at least you will come away having experienced its repugnant smell." [Bukhaari and Muslim]
