Dr. Marawan Shahin, Professor of Hadith and its Sciences, Faculty of Usul Ad-Din (Theology),Al-Azhar Univ. states: “Every tent can be used to make a congregation. It is not a condition or an obligation of Hajj to offer Zuhr and `Asr at the Sacred Mosque. However, it would far better to offer the Sunnah by offering them in the Haram. However, if you could not, then you can perform Zuhr and `Asr Prayers in congregation in your tent while shortening and combining them.”
Allah Almighty knows best.
