It is not common in other majority Muslim countries like Malaysia, Indonesia, present-day Iran, present-day Turkey and the majority of South Asia. These differences reflect different interpretations and understanding of Sharia regarding wearing a niqab. However, when performing Hajj or Umrah it is actually forbidden for the woman to cover the face, the rest is covered as when performing prayers. There is a difference of opinion among scholars with regards to how much should be uncovered for a woman in front of other women and a man in front of another man. In one hadith narrated by Abu Saʽid al-Khudri, the prophet said, "A man should not look at the private parts of another man, and a woman should not look at the private parts of another woman. A man should not lie with another man without wearing lower garment under one cover; and a woman should not be lie with another woman without wearing lower garment under one cover." (Abu Dawud – authenticated by Sheikh Naseeruddeen-al-Albani.) Relation with hijab Some Muslim women, particularly those living in some parts of the Middle East and South Asia wear the hijab headscarf. The type most commonly worn in the West is a rectangular scarf that covers the head and neck but leaves the face visible. Other styles also cover the hair, neck and shoulders completely, but the face and the hands are not covered, as they are not considered awrah for those Muslims who wear it. Female voice According to most scholars, the woman's voice is not (see quotation) awrah in principle, for according to the Hadith, women used to complain to the Prophet and ask him about Islamic matters. Also, according to the tradition, in the ritual prayer, a woman should invite the attention of the Imam by clapping, instead of saying "Subhanallah" which is for men. There is a difference of opinion whether or not a woman can recite the Quran when in the presence of non-mahram men. Certain scholars have concluded from the above differences that a woman's voice is also her awrah in some cases.
