In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
The Messenger (sallal-laahu-alayhi-wasallam) said:
ما ذئبان جائعان أُرسلا في غنم بأفسد لها من حرص المرء على المال والشرف لدينه
”Two hungry wolves let loose among sheep are not more harmful than a person’s craving after wealth and status is to his Religion.” [Ref 1]
Shaikhul Islaam Ibn Taymiyyah [rahimahullaah] said: He [sallal laahu alayhi wasallam] clarified that the corruption [caused] through craving for wealth and high status in the religion cannot be lesser than the corruption [caused] by two hungry wolves let loose among a livestock and that is [something] manifest; for indeed there is [nothing] of this craving in the sound religion. That is because when the heart tastes the sweetness of servitude to Allaah and love of Him, nothing else becomes more beloved, and by way of this evil and immorality are averted from the people who are sincere to Allaah. [Ref 2]
