إِنَّمَا مَثَلُ الْجَلِيسِ الصَّالِحِ وَالْجَلِيسِ السَّوْءِ كَحَامِلِ الْمِسْكِ وَنَافِخِ الْكِيرِ فَحَامِلُ الْمِسْكِ إِمَّا أَنْ يُحْذِيَكَ وَإِمَّا أَنْ تَبْتَاعَ مِنْهُ وَإِمَّا أَنْ تَجِدَ مِنْهُ رِيحًا طَيِّبَةً وَنَافِخُ الْكِيرِ إِمَّا أَنْ يُحْرِقَ ثِيَابَكَ وَإِمَّا أَنْ تَجِدَ رِيحًا خَبِيثَةً

The full narration
Abu Musa reported Allah's Messenger (ﷺ) as saying:The similitude of good company and that of bad company is that of the owner of musk and of the one (iron-smith) blowing bellows, and the owner of musk would either offer you free of charge or you would buy it from him or you would. smell its pleasant odour, and so far as one who blows the. bellows is concerned, he would either burn your clothes or you shall have to smell its repugnant smell
