Dr. Marawan Shahin, Professor of Hadith and its Sciences, Faculty of Usul Ad-Din (Theology),Al-Azhar Univ. states: There is no kaffarah required if one goes out for little shopping after Tawaf al-ifada and there is nothing wrong with the Hajj. However, it would be better if one makes their tawaf the last of what they do before leaving haram completely.”
Allah Almighty knows best.
