The times, they are a-changing, to quote Bob Dylan, and that is the case in the UAE as Muslim expats can now write UAE wills and distribute their assets exactly as they wish, in the same way as non-Muslims.
This is a huge change, and very welcome for many residents, especially those who have bought property in the UAE. Provided a will is set up correctly, and formally registered, assets will no longer be subject to distribution according to Sharia Law.
