Marriage in the 21st century faces new complexities from the speed of modern life and lack of patience, as well as unrealistic expectations. Problems include lack of role models, entitlement mentality, and lack of privacy. However, the Quran teaches that marriage's purpose is to find tranquility through love and mercy between spouses. Three key concepts are stillness (absence of disruptions), love (showing appreciation), and mercy (responding well to bad with good), qualities that help maintain a tranquil marriage.
