In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Ibn Abee Shaybah [rahimahullaah] reported in Al-Musannaf and Abu Nu-aym [rahimahullaah] in Al-Hilya [5/12] with an authentic chain from Abu Muslim Al-Khawlaani [rahimahullaah], who said: “The scholars are three types: A man who lives with his knowledge and the people live with it alongside him; a man who lives with his knowledge and none else lives with it alongside him, and as for the third man, the people live with his knowledge and it destroys him”. Shaikh Abdullaah Al-Bukhaari [hafidhahullaah] said, “The intent behind this speech: Indeed the first [man] knows, acts and teaches. As for the second, he knows and acts, but does not teach. As for the third, he knows and teaches, but does not act! We ask Allaah for steadfastness and well-being”.
