[Machine] "The believer to the believer is like a building, each part supporting the other. And the example of a good companion is like a perfume merchant; even if you do not buy from him, you will still be affected by his fragrance. And the example of a bad companion is like a blacksmith; even if he does not burn you, you will still be affected by his sparks. And the trustworthy treasurer who fulfills what he is commanded to do is like one who rents out to some of the benefactors."  

الْمُؤْمِنُ لِلْمُؤْمِنِ كَالْبُنْيَانِ يَشُدُّ بَعْضُهُ بَعْضًا وَمَثَلُ الْجَلِيسِ الصَّالِحِ مَثَلُ الْعَطَّارِ إِنْ لَمْ يُحْذِكَ مِنْ عِطْرِهِ عَلَقَكَ مِنْ رِيحِهِ وَمَثَلُ الْجَلِيسِ السُّوءِ مَثَلُ الْكِيرِ إِنْ لَمْ يُحْرِقْكَ نَالَكَ مِنْ شَرَرِهِ وَالْخَازِنُ الْأَمِينُ الَّذِي يُؤَدِّي مَا أُمِرَ بِهِ مُؤْتَجِرًا أَحَدُ الْمُتَصَدِّقِينَ
