An innovation (bidʿah) is anything introduced into the religion that is not part of it. The Prophet ﷺ said, “Whoever performs an action that is not in accord with our affair, it is rejected.” (2) Hence, every form of worship or devotional act by which a servant seeks nearness to Allah, but for which there is no proof in the Quran or the Sunnah, is an innovation. Even if its practitioner intends closeness to Allah, it only drives him further away; he earns no reward for it—rather, he is punished. The Sunnah, by contrast, is whatever rests upon evidence from the Book or the Sunnah.
