Ask the .ae registry. They might or might have those data. They might or might not make them available to you. It also depends on what you mean by historical data: zone file? query traffic? That's something you can discuss with the .ae registry too. You don't need to explain here what you mean.

ICANN requires gTLD registries to make their zone files available to anyone, subject to a few obvious conditions and requestors signing a zone file access agreement promising not to do naughty things with those data. I don't know (or care) if they keep historical copies of those zone files. This doesn't apply to ccTLDs because they don't have registry contracts with ICANN. Some ccTLDs make their zone data available under certain conditions according to their own policies. Others don't.
