Thanks for the question Veera... That is the problem with the Muslims TODAY. These things mentioned above is ISLAM. The things that Muslims practise today are CUSTOMS.
I feel sad for Taslima Nasreen. She was not treated correctly by her family members.
If you follow ISLAM, you should give woman the RIGHTS that ISLAM GUARANTEES. If not then I will be accountable to ALLAH and my wife/sister/daughter/mother on the day of Judgement.
