The exit showing on left is the door next to Hazrat Umar Farooq grave. If you make a little effort & want to enter from Bab-e-Jebril, sit next to the door before Asar prayer.
Bab-e-Jebril door is not open all the time, you can see a white wall which is actually a temporary partition. Sit next to the partition before Asar prayers & you will find a place inside next to Prophet(P.B.U.H) for Asar prayer:). Don't miss it.
