ذِكْرُ الْأَمْرِ بِمُجَالَسَةِ الصَّالِحِينَ، وَأَهْلِ الدِّينِ دُونَ أَضْدَادِهِمْ مِنَ الْمُسْلِمِينَ
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." (Using translation from Bukhārī 5534)
عَنِ النَّبِيِّ ﷺ قَالَ «مَثَلُ الْجَلِيسِ الصَّالِحِ وَمَثَلُ جَلِيسِ السُّوءِ كَحَامِلِ الْمِسْكِ وَنَافِخِ الْكِيرِ فَحَامِلُ الْمِسْكِ إِمَّا أَنْ تَبْتَاعَ مِنْهُ وَإِمَّا أَنْ تَجِدَ مِنْهُ رِيحًا طَيِّبَةً وَنَافِخُ الْكِيرِ إِمَّا أَنْ يُحْرِقَ ثِيَابَكَ وَإِمَّا أَنْ تَجِدَ مِنْهُ رِيحًا خَبِيثَةً»
