Narated By A man : AbuSallam told that he was in the mosque of Hims. A man passed him and the people said about him that he served the Prophet (pbuh).
He (AbuSallam) went to him and said: Tell me any tradition which you heard from the Apostle of Allah (pbuh) and there were no man between him and you. He said: I heard the Apostle of Allah (pbuh) say: If anyone says in the morning and in the evening: "I am pleased with Allah as Lord, with Islam as religion, with Muhammad as Prophet," Allah will certainly please him.
