Question: when to do tawaf e ziarat?
Answer: I would recommend Tawaf-e Ziyarat with old people to be offered late and not in day as it is way too crowded, however it is Afzal doing it the first day. You have to spend at least half the night in mina. Spending 4 hours after maghrib is good enough. You wear Ihram again and leave for Tawaf at 12:30 AM.
