Keeping the company of righteous people and attending their gatherings is one of the qualities of goodness, and a way to attain happiness in both the worldly life and the Hereafter. Likewise, keeping the company of wicked and evil people isa sign of wickedness and the path to loss and ruin. In this hadeeth, the Prophet ﷺ gave a good similitude of the two categories of people: a good (righteous) companion and a bad (evil) one, to help us better understand the intended meanings, and urge us to adhere to what is good and avoid what is evil. The first category in the hadeeth is the righteous companion, a pious person who directs his companions to Allah, Exalted is He, and guides them to the sayings and deeds that bring them closer to Him. The Prophet ﷺ likened such a good companion to the musk seller. Keeping his company yields benefits in all cases; you either buy musk and perfume from him or simply enjoy the pleasant smell. Likewise, a good companion may bring you some tangible benefits or you may simplyfind comfort and joy in his company. The second category is the bad companion, who drives those in his company away from Allah, Exalted is He, and all sayings and acts that draw them closer to Him. In this hadeeth, the Prophet ﷺ likened a bad companion to blacksmith's bellows (or furnace), meaning to a blacksmith. The Arabic word used in the hadeeth ‘Keer’ means a bag-like device made of thick leather (with handles) that is used to blow air onto a fire to keep the flame burning. Such a blacksmith (who blows air onto a fire) will either burn your body or clothes with the sparks, or make you smell an unpleasant odor, causing you distress and inconvenience. Likewise, a bad companion either causes you direct harm by committing sins with him, and accordingly suffering their burning flames, or by witnessing firsthand his ugly and evil deeds and therefore being dispraised for keeping the company of such a wicked person. The hadeeth urges Muslims to keep the company of righteous and obedient people, and keep away from wicked and ill-mannered ones. .
