If a company was registered for VAT voluntarily.

Are they aloud to claim the input VAT on capital assets bought before their VAT registration?

I read an article that it was allowed, but it was an article in 2013/2012. No sure if it is applicable, anddo not see anything like that in the law.
On the one side I feel that it should be since, when the assets is sold their will be VAT output tax, but do not want to claim something that is not allowed.

If anyone has done that before, can you please tell me.
