In GCC countries, I have observe normally Eid salath is performed after Shurook time is finish (over) i.e. when Ishraq namaz time begins..here in Qatar Shurook time begins at 5:30 am and ends after 15 minutes. InshaALLAH tomorrow Eid al Adha salath will be at 5:45 am or later.(2-3 minutes difference across qatar)
