What are the rights of the wife to her deceased husband's property, and does this include the deferred dower and the 'iddah (waiting period) maintenance? How is the 'iddah maintenance calculated, and do her debts from her husband take precedence over the debts of strangers?

The deferred dower is a debt owed by the husband to his wife, which she is entitled to receive from his estate before its division. The wife shares in it with other creditors. As for maintenance during the 'iddah (waiting period), it is forfeited upon the husband's death because the marital bond has ceased.
