question #1 Sahih Muslim 758a, Book 6, Hadith 201 : What is the significance of the last third of the night in Islamic worship and supplication?

Our Lord, the Blessed and the Exalted, descends every night to the lowest heaven when one-third of the latter part of the night is left, and says: Who supplicates Me so that I may answer him? Who asks Me so that I may give to him? Who asks Me forgiveness so that I may forgive him?
