A sister wants to know if the Niqab is obligatory? Also what about the position of Shaykh Al Albani in this issue ? And it was narrated from Aishah that Asma bint Abi Bakr رضي الله عنهم entered upon the Messenger of Allah صلى الله عليه وسلم wearing a thin garment. The Messenger of Allah صلى الله عليه وسلم turned away from her and said: “Oh Asma, when a woman reaches the age of menstruation, it is not proper for anything to be seen of her except this and this,” and he pointed to his face and hands. Is this Hadith weak? And lastly how did the Salaf understand the verse " وَلَا يُبْدِينَ زِينَتَهُنَّ إِلَّا مَا ظَهَرَ مِنْهَاۖ and not to show off their adornment except only that which is apparent " [24:31]
