In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
The Messenger [sallal-laahu-alayhi-wasallam] said: “The over-stringent ones are destroyed.”
Imaam Nawawi [rahimahullaah] said: “The over-stringent ones are those who look too deeply [into affairs] and are excessive- those who exceed the Hudood [prescribed legislated sharia boundaries] in their statements and actions”.
