Has anyone wrote an islamic will? If so any pointers what we should consider?

For those of you living in the UK would you recommend getting in touch with solicitors to make your will legally binding?

I don't have any quotations but i am led to believe this is faraz upon us as believers to leave a will.

Of course it does not need to be all about financial assets but about your funeral arrangements and whether you would like to be in a coffin or shrouded, where you would like to be buried etc.

Any ideas, thoughts, comments would be much appreciated.

Jazaka Allah.
