Hejab and chastity" are familiar terms in the human lexicon that have gone through many ups and downs over time from tradition to modernity. Meanwhile, men and women (especially women) in the rushing wind of movement toward modernism were exposed to cultural nudity and a culture of nudity in order to play their part in the development of capitalism. However, over time, they drifted further away from their identity, personality, and essence, and in a new movement, by returning once again to their selfhood and paying attention to their nature, disposition, and true needs amidst spirituality, they sought their identity in "chastity and hejab." A look at the foundations of "hejab and chastity," which stem from the truths of religion and are formulated and explained on a horizon higher than the material world, in the era of nudity, is the only positive and true response to inner needs and a return to the innate tendencies of human society that creates health, security, spirituality, and perfection in the family and society; and this choice is the only way to reach divine perfection and felicity.
