The wife of Prophet Muhammad who would go out at night for natural relief is commonly identified as Umm Salama Hind bint Abi Umayya. According to Islamic traditions and historical accounts, Umm Salama had a habit of going out at night to a designated area for personal needs, and Prophet Muhammad permitted her to do so.

The hijab came to pictures because of Umar bin Abd Khattab who advised Mohammad to veil his wives, because they are seen vividly when they get out in the night to attend the nature calls. It started with Umayya because she was a big and staut person. She is vivid in the night. This information is explained in Sahih al Bukhari 146 and Sahih Muslim 26 : 5395.The first burgha is full body with s small hole near the eyes. Mohammad always supported by Allah. Any surah he wanted will be immediately given. Great.
