Praise be to Allah.
There is no basis for saying that cutting the nails at night is haram; rather a person may cut his nails whenever he wants, at any time of day or night.
Similarly, there is no basis for saying that one must say Bismillah three times over nails or hair before throwing them away, otherwise the Shaytan will use them.
It is also not correct to say that they must be buried ; a hadith was narrated concerning that which is very weak.
It is permissible to throw them in the garbage or down the drain , or to bury them. If a person fears that they may fall into the hands of those who practice sihr (witchcraft) then he should dispose of them in a place where they will not be able to get hold of them.
And Allah knows best.
