I have observed that during Ramadhaan, women had gone for Umrah sit outside Musjid Nabawi in groups for Iftaar.

Answer

When it is not permissible for these women to be even inside the Musjid for Salaat, how can it ever be permissible for them to sit in groups outside the Musjid eating like dogs and labelling their stunt as 'iftaar'? They are lewd women who resort to such tricks and stunts to give expression to their nafsaaniyat.
