proof that it is islamic...and not like you said QATARI CULTURE...

"Ayesha (r) reported that Asma’ the daughter of Abu Bakr (r) came to the Messenger of Allah (s) while wearing thin clothing. He approached her and said: 'O Asma’! When a girl reaches the menstrual age, it is not proper that anything should remain exposed except this and this. He pointed to the face and hands." [Abu Dawud]

 

Ibn Qudama in al-Mughni (1:349) explained that showing the face and hands are a specific dispensation within the general meaning of the hadith "All of the woman’s body is considered her nakedness [to those outside the mahram relationship or her husband]." (al-mar'atu `awra)
