Someone asked a saint, "Why is it that the stench of backbiting was smelt during the time of Rasulullah 
but is not evident today?"
He replied,"Backbiting has become so common nowadays that it's stench has disappeared. The example is like how a toilet cleaner and a tanner become so accustomed to the stench of faeces and raw leather, that they can eat quite comfortably in their environments whereas others will find it difficult to even stand there for a moment. This is how backbiting has taken vogue today!"
(Tambi-ul-Ghafileen, Faqih Abu Laith Samarqandi A.R)
