Where to Throw Cut Nails in Islam?
Question

Is it correct that throwing away one’s nail clippings is prohibited and that they should be buried?
Praise be to Allah.Islam tells us to trim our nails , because this is one of the five qualities dictated by the Fitrah (natural inclination of man). If one throws them in the garbage or buries them , there is nothing wrong with doing either. (Fatawa Al-Lajnah Ad-Da’imah, 5/174). 
But if one is afraid that they may fall into the hands of a practitioner of Sihr (witchcraft), then he should bury them or throw them somewhere where such people will not be able to get their hands on them.

And Allah knows best.
