Imam Ali (AS) said, It is enough of an error for a person to command others to do what he does not do [himself] and forbids them from that which he does not refrain from.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : كَفى بِالمَرْءِ غَوايَةً أنْ يَأمُرَ النّاسَ بِما لا يَأْتَمِرُ بِهِ وَ يَنْهاهُمْ عَمّا لا يَنْتَهي عَنْهُ
