Hadith narrated by Abu Hurairah Radliyallahu 'anhu, he said: One day, the Prophet sallallaahu 'alaihi wa sallam appeared among the Muslims. Then came a man and asked: Messenger of Allah, what is the Faith? The Prophet sallallaahu 'alaihi wa Sallam replied: You believe in Allah, His angels, His books, meeting with Him, His apostles and to the day of resurrection.
