COMPARISON BETWEEN A RIGHTEOUS AND EVIL COMPANION H 364 "The comparison between a righteous Companion and an evil Companion can be likened to one who carries perfume and another who blows at a flame in a furnace. The one who carries perfume may give you some as a gift, or you may buy some from him, or at least, you may smell its fragrance. As for the other, he may set your clothes on fire, or at the very least you may inhale the fumes of the furnace." R 364 Bukhari and Muslim with a chain up to Abu Musa Ash'ari who related that the Prophet, praise and peace be upon him, said this.
363- وعن أَبي موسى الأشعري رضي الله عنه أن النبي صلى الله عليه وآله وسلم ، قَالَ : "إِنَّمَا مَثلُ الجَلِيسِ الصَّالِحِ وَجَلِيسِ السُّوءِ ، كَحَامِلِ المِسْكِ ، وَنَافِخِ الْكِيرِ ، فَحَامِلُ الْمِسْكِ : إمَّا أنْ يُحْذِيَكَ ، وَإمَّا أنْ تَبْتَاعَ مِنْهُ ، وَإمَّا أنْ تَجِدَ مِنْهُ ريحاً طَيِّبَةً ، وَنَافِخُ الكِيرِ : إمَّا أنْ يُحْرِقَ ثِيَابَكَ ، وَإمَّا أنْ تَجِدَ مِنْهُ رِيحاً مُنْتِنَةً" مُتَّفَقٌ عَلَيهِ . ( يُحْذِيكَ ) : يُعْطِيكَ .
