´Anas bin Malik narrated that the Messenger of Allah(s.a.w) said:` "Before the Hour there shall be Fitan like a portion of the dark night. Morning will come upon a man as a believer, who will be a disbeliever in the evening, and evening will come upon a believer, who will be a disbeliever in the morning, people will sell their religion for goods of the world."
