Tolstoy opens Anna Karenina with a sentence that has outlived the plot it introduces: “Happy families are all alike; every unhappy family is unhappy in its own way.”
We read it as a remark about domestic life, but it is really a claim about the shape of good and bad. Flourishing converges on a single form; failure scatters into many. A happy household rests on the same handful of things—trust, patience, some working measure of forgiveness. Remove any one of them and the house can come apart in a thousand unrelated ways: this one through resentment, that one through neglect, another through pride. There is a narrow road into happiness and a wide field of exits from it.
The Quran carries the same intuition, but it encodes it in grammar. Light—nūr—is kept singular. Darkness—ẓulumāt—is cast in the plural. The distinction is easy to miss in English, where “darkness” and “light” both sit there as bare nouns. It lives in the Arabic:
يُخْرِجُهُم مِّنَ الظُّلُمَاتِ إِلَى النُّورِ
yukhrijuhum mina aẓ-ẓulumāti ilā an-nūr—He brings them out of the darknesses (plural) into the light (singular).
The central verse says it in full:
“GOD is Lord of those who believe; He leads them out of darkness into the light. As for those who disbelieve, their lords are their idols; they lead them out of the light into darkness—these will be the dwellers of Hell; they abide in it forever.” (2:257)
Notice that the verse describes two movements—out of the darknesses toward the light, and out of the light toward the darknesses—and keeps the same count in both directions. Even the fall preserves the grammar. You do not descend into a darkness; you descend into darknesses, plural, one after another with no floor.
The logic is the plainest thing in the world once you see it. A target has one center and an unlimited margin. There is one way to add a column of figures correctly and endless ways to get it wrong. A key fits one lock; the wrong keys are without number. Truth is one because it answers to how things actually are, and reality does not offer alternatives to itself. Error is many because it is simply any departure from that one thing, and there are infinite directions in which to depart.
The verse doubles the pattern in a detail worth pausing on. The believers have a Lord—one, named. The disbelievers have lords, plural: “their lords are their idols.” One turns toward a single source and is drawn toward a single light. The other divides his loyalty among many masters and is pulled apart among many darknesses. Fragmentation is not the punishment tacked on at the end; it is the condition itself. To leave the one is already to be scattered.
This is why the darknesses are so various and the light so plain. Every idol promises something different, so every false path has its own texture, its own private logic, its own way of seeming reasonable from the inside. That is the whole difficulty of error—it is not monotonous. It is inventive, particular, endlessly renewed, which is exactly why it can look richer than the truth it left behind. Tolstoy’s unhappy families are fascinating for the same reason: each has found its own unrepeatable way to fall.
But variety is not depth. The thousand darknesses are not a thousand destinations; they are a thousand ways of missing the one. And the light does not need to compete with them by multiplying. It only has to be what it is.
Many darknesses, one light.
