Awrah is a part of the body from the navel to the knees. The navel does not belong to awrah, however 1 millimeter below the border of the navel is included in awrah, therefore it is obligatory to close it. The knee that connects the thigh and lower leg is also included in awrah.
The information was received from the member of the World League of Scientists Ahli Sunna and the ex - mufti of the Kyrgyz Republic - Chubak azhy Zhalilov.
Also Shafi'i theologians believe that the awrah of a man is that part of the body that is between the navel and the knee. The navel and knees do not belong to the awrah, but it is recommended to cover them in order to avoid accidentally opening awrah.
