Answer
(Fatwa: 368/346=N)
(1) Holding this view is tantamount to kufr since hijab is proved from Quran:
وَإِذَا سَأَلْتُمُوهُنَّ مَتَاعًا فَاسْأَلُوهُنَّ مِنْ وَرَاءِ حِجَابٍ
And when ye ask (his ladies) for anything ye want, ask them from before a screen (33/53)
يَا أَيُّهَا النَّبِيُّ قُلْ لأزْوَاجِكَ وَبَنَاتِكَ وَنِسَاءِ الْمُؤْمِنِينَ يُدْنِينَ عَلَيْهِنَّ مِنْ جَلابِيبِهِنَّ
O Prophet! Tell Thy wives and daughters, and the believing women, that They should cast their outer garments over their persons (When abroad) (33/59)
(2) This view is completely wrong, though did not constitute kufr.
(3) This view is also kufr since it contradicts this ruling of Quran:
وَالسَّارِقُ وَالسَّارِقَةُ فَاقْطَعُوا أَيْدِيَهُمَا جَزَاءً بِمَا كَسَبَا نَكَالا مِنَ اللَّهِ
As to the thief, male or female, cut off His or Her hands: a punishment by way of example, from Allah (5/38)
