Q:

1. It comes in the Hadith about zuhr sunnats that time the heavens are open. Does that mean we should read our zuhr sunnats immediately after zuhr time begins to get this virtue. 
2. How do you work out zuhr begining time? When is zawaal how long before zuhr? If zuhr starts at 1:12. Can you read nafl at 1:00. If zuhr starts at 1:12, can you read sunnats after Azaan? I heard you should wait 5 minutes. Why is that?
3. Sun rising, setting and zawaal you can't read anything. Can you bury someone at that time?
