Mukhtasar Muslim (Abridged) 2038 — Hasten to good deeds before severe

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Hasten to do good deeds before the trials that will be like the dark parts of the night. A man will be a believer in the morning and a disbeliever in the evening, or he will be a believer in the evening and a disbeliever in the morning, and he will sell his religion for the goods of this world.
