It is narrated from Sayyiduna Miqdad bin Aswad (may Allah be pleased with him), he says: After hearing a hadith of the Noble Prophet (peace and blessings be upon him), I do not make any judgment about the goodness or evil of any person until I see on which deed his life ends. Someone asked: Which hadith have you heard? I said: I heard the Messenger of Allah (peace and blessings be upon him) say: The heart of the son of Adam turns more frequently than a pot that is boiling completely.

Benefits: … The people of earlier times were steadfast and firmly established upon their respective beliefs; in the present era, qualities such as dignity, composure, and seriousness are becoming increasingly rare. One aspect of this is that it is no longer apparent when people shift from good deeds to evil deeds, or from evil deeds to good deeds. What is most prevalent is that people’s hearts are becoming empty of the recognition and love of Allah Ta‘ala and His Messenger (sallallahu alayhi wa sallam), as a result of which there is a great increase in misconduct.
