Despite the restriction, symbolism was incorporated into many aspects of Islam. Symbols are employed to demonstrate a connection to Islamic ideas and customs. “Those who inhabit paradise will wear magnificent silk clothes of green,” according to the Quran (Surah 18:31). As a result of how this scripture has been understood over the centuries, the color green has long been connected with Islam (though not officially). Green bindings are used on Qurans, mosques are ornamented with green as the dominating color, Sufi saints’ graves are wrapped in green silk, and green is prominently featured in the flags of several Muslim countries.
White is a color that is commonly associated with tranquility and purity. For Friday prayers, many Muslims dress in white. In many cultures around the world, black is a symbol of grief, but in Islam, it is a symbol of modesty. Red is a common color on the flags of Muslim countries, despite its lack of significance for Muslims.
Green, black, white, and red are the four primary colors featured in the flags of most Arab countries.
