11.  Salman  was  passing  by  a  graveyard.  He  said,  “O believers  and  Muslims  residing  inside  the  graves,  my salutations be upon you. O those who are lying here! Do you  know  that  today  is  Friday?”  He  returned  home  and slept. He saw a man in his dream who said, “O servant of Allah! Salutations be upon you too. We heard whatever you said. You saluted us and we are giving you the reply. You had  asked  us  whether  we  knew  that  today  is  Friday.  We even know what birds say on Friday.” Salman asked, “What do birds say on Friday?” The man replied, “They say: Pure is our Glorious Allah Who is Great and there is none like Him. A person who swears falsely for the Lord is not aware of His greatness.”
