Yes, the Will/Wasiyyah completed on Manzil Wills is compliant with Islamic law as it was reviewed and approved by well-known scholars. For more details, you can see our Shariah Advisory Board here and our Certifications here. However, as with any Will, there is a possibility it may be challenged in court. If you have specific questions or problems related to the making of your will, we advise you to contact a lawyer and/or consult an Imam to ensure all your needs are covered.
