Performing tawaaf on the second and third level
Q: If a person performs tawaf in the lowest floor around the ka'bah (ie. the sahn floor), it is likely that he will (unintentionally) come in physical contact with women due to the crowd, especially close to the al-hajar al-aswad corner. Will he still be permitted to perform tawaf on this floor (whilst doing his best to avoid contact), or is it wajib for him to perform the tawaf on any of the higher floors where the risk of contact is less?
