Can you marry your cousin?

We can marry our cousin according to Islamic sharia law. Well, if you go world wide marrying cousin is not accepted or feel to be awkward at least. The reason behind is, in most of the country like India. We Indian, we are too close to our cousin sister and brother. We have feeling of brother and sister. Even though there is always exception because individual feeling.

Islamic sharia permits.

but hindu law prohibits.

so its purely religious and respective tribes in some cases as well. thanks.
