'Do not be like he who...exhorts extensively but does not take lesson himself, as he is arrogant in his speech and little in Success (tawfiq) deeds, he challenges for what is to perish, and allows to pass what is eternal, he sees benefits as a loss, and losses as beneficial.'
Imam Ali ibn Abi Talib [as]
Nahj al-Balagha, Saying 150 .
