You should never cut back the leaves of ANY bulb after flowering, at least not until the leaves have truned brown and dried up. They make food to feed the bulb so you get flowers next year. Even the dying leaves have a function, in that sugars in them a taken back into the roots as they die. You should not tie them in bundles as some folks do either. Leave them alone!
You may even find it useful to feed the bulbs after flowering too. I use a foliage type feed sprayed on to the leaves. If the bulbs are in posts and you need to use the pots then you may carefully remove the bulbs and soil and put it somewhere out of the way in the garden to die down naturally.
By the way, the only silly question is the one you did not ask when you could have done!
