Why shouldn't you cut your nails at night in Islam?

Is it Permissible to Cut Nails at Night in Islam?
There is no Islamic prohibition against cutting nails at night; individuals are free to do so at any hour, whether day or night. Additionally, the notion that one must recite Bismillah three times over their nails or hair before disposing of them, or else the Shaytan might use them, is not supported by any sound basis.
