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.”
