Narrated Abu Musa: The Prophet (ﷺ) said, 'The example of a good pious companion and an evil one is that of a person carrying musk and another blowing a pair of bellows. The one who is carrying musk will either give you some perfume as a present, or you will buy some from him, or you will get a good smell from him, but the one who is blowing a pair of bellows will either burn your clothes or you will get a bad smell from him."

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَثَلُ الْجَلِيسِ الصَّالِحِ وَالسَّوْءِ 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 ‏"‏‏.‏
