The concept of wasiyyah is well known, yet often misunderstood. Many Muslims assume they can distribute their entire estate freely through a will, not realising there are clear limits.

Under Islamic inheritance principles, only up to one third of an estate may be given to non-fixed beneficiaries, such as charities or extended relatives. The remainder is allocated to fixed heirs.

Problems arise when this distinction is not properly understood or documented. Without a correctly structured will, intentions may not be carried out as expected, causing confusion and disappointment.

In the UK, a will must also comply with English law to be enforceable. This means Islamic intentions need to be expressed in a legally recognised format.

A properly prepared Islamic will ensures the one-third rule is respected, fixed heirs receive their shares, and charitable intentions are fulfilled without uncertainty.
