It was narrated that Anas bin Malik said:"The Messenger of Allah said: 'I have been tortured for the sake of Allah as no one else has, and I have suffered fear for the sake of Allah as no one else has. I have spent three days when Bilal and I had no food that any living being could eat but that which could be concealed in the armpit of Bilal
