Disposing of Hair and Nails

Disposing hair

Q: If a person shaves his moustache over the bathroom sink every morning, would this be OK even though the stubbles of hair will go down the drain? Or does he have to shave over a container to collect the stubbles of hair in order to bury them?

Burying hair

Q:

1. Must the hairs that collect on the comb/brush be buried?

2. Must the hairs that fall out when combining/brushing the hair be collected and buried?

3. Must the hair removed from the eyebrows, nose, mustache, chest, legs, etc. all be buried?

4. When having a shower/bath, hairs that fall off sometimes tangle up together around the drain. Must this be buried?

Burying hair

Q: Please tell me what Ii should do with my fallen hair which I have collected since 10 years. I am not throwing it out because I don't know where to throw it? If I throw it in the sea, won't it cause harm to the fish? Shall I bury it in a Muslim graveyard?
