Adoption as a single parent in dubai

Dear All,

Since some years back I had the idea to adopt a child. However, i was told that it was not allowed in islamic countries. Since i read some posts stating that in fact it is possible i understand there is some hope after all.

Is there any restriction to adopt a child from Ethiopia or any other country being a single parent in Dubai?

Do you know of any organization I could approach in order to find out? Is the whole adoption process very long or expensive?

Im originally argentinian although my place of residence out of uae is in Spain.
I would very much appreciate any advise or any kind of help. Thanks,

clau
