Imam Ali (AS) said, Be cautious of the fool when you are in his company, of the vicious when you associate with him and of the oppressor when you deal with him.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : كُنْ عَلى حَذَر مِنَ الأحْمَقِ إذا صاحَبْتَهُ وَ مِنَ الفاجِرِ إذا عاشَرْتَهُ وَ مِنَ الظّالِمِ إذا عامَلْتَهُ
