(1) On the 8th of Dhul-Hijjah, some enter into ihram, perform tawaf and sa‘i, and then depart for Mina; on the 10th, they perform tawaf but do not perform sa‘i. This is incorrect. The correct practice is to depart for Mina after entering into ihram, without performing tawaf.
(2) Some people depart for Mina before sunrise. This is also incorrect.
