Al- Husayn (a.s.) performed separate al-‘Umrah in Dhu al-Hijjah, then he left on the day of al-Tarwiyah (8th of Dhu al-Hijjah) for Iraq when people were leaving for Mina. There is no offense in performing al-‘Umrah in the month of Dhu al-Hijjah if one does not want to perform al-Hajj.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/234))
