question #1 Sahih Muslim 758c, Book 6, Hadith 203 : What is the significance of the time during the night when Allah descends to the lowest heaven?

When half of the night or two-third of it is over. Allah, the Blessed and the Exalted, descends to the lowest heaven and says: Is there any beggar, so that he be given? Is there any supplicator so that he be answered? Is there any beggar of forgiveness so that he be forgiven? (And Allah continues it saying) till it is daybreak.
