It is reported from the famous worshiper Rabi'ah al-Adawiyya (radiAllahu anha) that she said: "I have never heard the adhaan except that I remember the caller who will announce the Day of Resurrection, and I never see the falling snow except that I imagine the flying pages of the records of peoples deeds (on that day), and I never see swarms of locusts except that I think about the Great Gathering on the Last Day."
