Hadith 146فَالنَّاسُ عَلَى أَرْبَعَةِ أَصْنَافٍ: مِنْهُمْ مَنْ لاَ يَمْنَعُهُ الفَسَادَ في الاْرْضِ إِلاَّ مَهَانَةُ نَفْسِهِ، وَكَلاَلَةُ حَدِّهِ وَنَضِيضُ وَفْرِهِ
People are of four categories. Among them is one who is prevented from mischief only by his low position, lack of means and paucity of wealth.
