Your time in Mecca
1) Carry your sandals/shoes with you in a plastic bag when in Al Masjid Al-Haram. Do not leave on the shoe rack for you might forget where you have left them. Bring a prayer rug with you.
2) Try not to drink too much water before you start your Tawaf or Sa'ayyi. You can make up for that at the end. Rest rooms are extremely congested.
3) Remember the gate number when you enter the Mosque. Look around you for landmarks that can guide you back. The King Fahd gate is the most recent addition at this time and that section is air-conditioned.
4) Try to perform Umrah late in the evening 2 hours before Al-Fajr prayer. Least congested.
5) Don't exit right after the jama'ah prayer at Al-Haram mosque. Wait at least 15 minutes to avoid the crowds.
6) Consider the second or third level of AL-Haram Mosque when performing Tawaf Al Ifadah and Al Wada'a. 'During Tawaf at the main level, try to move to your right as you approach the black line that runs across from the black stone to a nearby green light hanging on the wall. Also, carry with you a pocket Koran and a Dua'a pocket book during Tawaf and Sa'ayyi.
