He said that God's messenger told them two traditions one of which he had seen happen and was looking forward to the other. He told them that faith had come down into the roots of men's hearts, then they gained knowledge from the Qur'an, then gained knowledge from the sunnah. He also told about its removal, saying, "A man will sleep [2] and faith will be taken from his heart, but its mark will remain like the mark of a spot. He will sleep again, and it will be taken away, its mark remaining like the mark of a blister, as when you drop live coals over your foot a water blister is produced and you see it swollen with nothing in it. People will make business agreements with one another and scarcely one will fulfil his trust. It will then be said that among the B. so and so there is a trustworthy man. People will remark how intelligent, excellent, and resolute a man is while he has not as much faith in his heart as a grain of mustard seed." 1. Fitan pl of fitnah. There are different meanings, e.g., temptation, seduction; discord, commotion, civil war; testing, trial; impiety, unbelief. 2. This may either be understood literally, or as a figure of speech for carelessness. (Bukhari and Muslim.)
