Your Sharia compliant Will must always contain a declaration of faith, also known as the shahada.

This is a basic statement that declares that you are a Muslim and abide by the Shariah.

It is a necessary statement to be included as part of any Islamic Will and will be a declaration of the following statements:

-  There is no God besides Allah

-  Muhammad is the Messenger of Allah

-  Paradise is true, and Hell is true.

- The coming of the Day of Judgement is true, there is no doubt about it, and that Allāh, Who is exalted above all deficiency and imperfection, will resurrect the dead of all the generations of mankind.

The reason why the Declaration of Faith is so important is that this declaration is considered to be the foundation of the Islamic faith and is the first of the Five Pillars of Islam. It is important because it is the declaration of one's belief in the oneness of God and the belief in Prophet Muhammad as his messenger. It is also the act of becoming a Muslim. It is recited daily by Muslims in their prayers and is considered to be a declaration of one's submission to God.

Certain requirements must be met in order for the Shariah Will to be considered valid. One of these requirements is that the person making the Will must be a Muslim, and this is typically demonstrated by a declaration of faith (shahada). If there is no Declaration of Faith, it may be difficult to prove that they were Muslim, and their Will may not be considered valid under Sharia.
