مناسك حج - مكارم شيرازى، ناصر - الصفحة ٢٢٥ - Umrah al -Mufradah
٤- When there are lots of people performing Tawaf in the way that crowd push the person forward by force and involuntarily, it does not harm Tawaf, and it is enough to make the intention from the beginning that he/ she goes among people for performing Tawaf.
٥- The place for performing the prayer of obligatory Tawaf is behind Maqam of Ibrahim, but it can be performed more distant from there if the crowds are so much congested; the pilgrim should not insist on performing the prayer behind Maqam, specially when performers of Tawaf are so much that they reach behind Maqam of Ibrahim and some acts that some commons perform and disturb performers of Tawaf are not correct( but the prayer of Mustahab Tawaf can be performed anywhere in Masjid al- Haram ).
