Islam enjoins women to cover their bodies, and to wear hijab and loose garments that do not show the body or show its shape. In this hadith, the Mother of the Believers ‘A’ishah (may Allah be pleased with her) narrates that the Prophet (blessings and peace of Allah be upon him) used to pray Fajr when it was still dark. What is meant is the darkness at the end of the night, after dawn has broken. This is a metaphor which indicates that the Prophet (blessings and peace of Allah be upon him) used to pray Fajr at the beginning of its time. The women would leave and would not be recognized because it was so dark. This means that the women would hasten to leave the mosque after the prayer had finished, when it was still dark, so they would not be recognized because of the darkness. After hijab was enjoined, the women of the Sahabah (may Allah be pleased with them) adhered to it and did not show anything of their adornment except what Allah had permitted. This hadith indicates that it is permissible for women to go out and pray in the mosques..
