It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Perform good deeds before the tribulations that will come one after another like the darkness of night. A time is coming when a man will be a believer in the morning, but by evening he will have become a disbeliever, or he will be a believer in the evening, but by morning he will have become a disbeliever. He will sell his religion for a small portion of worldly goods.
