Hijab and hijab cannot be separated from the lives of Muslim women. A Muslim woman must wear a hijab and a headscarf when she is an adult or when she has had menstruation. Islam is a religion that regulates all aspects of life including the manner of association and how to dress properly and properly. Headscarves have become part of the association and life of a Muslim woman and one of the characteristics of a woman who is good according to Islam is wearing a hijab or headscarf.
The command of the headscarf was revealed at the time of the Prophet Muhammad. History says that the command to wear a veil and wear a hijab came down when the Prophet often held a banquet together with his guests. Because guests are invited to the house of the Prophet then while eating and chatting they are free to enter the house of Rasul SAW. This has the potential to cause slander where the wives of the Apostle at that time did not yet wear the hijab
The Law of Wearing a Hijab
Wearing a headscarf and covering the aurat is obligatory for every Muslim woman and this has been mentioned in the arguments regarding the order of the hijab above. The veil of a woman should cover the genitalia, which means the whole body except the palms and faces, as mentioned in the following hadith concerning the law of wearing a headscarf:
The obligation to cover the genitals other than the face and palms
In wearing a headscarf a woman must cover all her nakedness as mentioned in the following hadith
"Aisyah R.ah said: Asthma 'bint Abi Bakar met Rasul SAW in thin clothes, at once the Apostle SAW turned away saying: Hi Asma', actually if a woman has menstruation, it is no longer natural to see her except this and this (she points to her face and both hands)
The obligation to maintain the genitals of the opposite sex who are not mahram
Likewise about the female genitalia that must be covered with hijab from the view of other people who are not mahram mentioned in the Al-Qur'an letter An Nur verse 31 below
وقل للمؤمنات يغضضن من أبصارهن ويحفظن فروجهن ولا يبدين زينتهن إلا ما ظهر منها وليضربن بخمرهن على جيوبهن ولا يبدين زينتهن إلا لبعولتهن أو آبائهن أو آباء بعولتهن أو أبنائهن أو أبناء بعولتهن أو إخوانهن أو بني إخوانهن أو بني أخواتهن أو نسائهن أو ما ملكت أيمانهن أو التَّابِعِينَ غَيْرِ أُولِي الْإِرْبَةِ مِنَ الرِّجَالِ أَوِ الطّ فل الذين لم يظهروا على عورات النساء ولا يضربن بأرجلهن ليعلم ما يخفين من زينتهن وتوبوا إلى الله جميعا أيه المؤمنون لعلكم تفلحو
"Say to the woman who has faith:" Let them hold their eyes, and their genitals, and let them not show their jewelry, except those (ordinary) that appear from them. And let them cover the veil of the cloth, and do not show off their jewelry except to their husbands, or their fathers, or their husbands' fathers, or their sons, or the sons of their husbands, or their brothers or sons or the sons of their brothers, or the sons of their sisters, or Muslim women, or slaves they have, or male servants who have no desire (towards women) or children who do not understand about women's genitals. And let them not strike kakinyua so that the jewelry they hide is known. And repent all of you to Allah, O you who believe so that you will be lucky "(QS An Nur verse 31)
