The Muslim Holy book Quran contains texts, and Hadith is a collection of narrations of Prophet Muhammad Sallallahu Alayhi Wasallam. There are online Islamic inheritance calculator apps available that incorporate the doctrine of Radd (i.e., proportional increase) and Awwal (i.e., proportional decrease) applies to fixed or prescribed shares (Ashab al-Furudh). If Residuary (al-Asabat), then the doctrine of Radd is not applicable. The final calculated shares must account for after debts (loans, mortgages, etc.), burial or funeral expenses, legal and administration costs for executors and trustees, obligatory religious debts, succession taxes, and testamentary bequests (al-wasiyya). Distant kindred (Dhawul Arham) inherits if neither fixed nor residuary survives, except distant kindred do inherit in the presence of Husband or Wife. The calculated shares will be in fractions, percentages (%), or both.

Any individual, lawyer, or judge can use these online calculators can be used without requiring prior knowledge; however, they can be used carefully as they may have some inaccuracy or errors due to reliance on computer programming codes, and if needed, validations with scholars or Mufti are to be done, especially if utilized for estate distribution. However, it will not give you heart touching feeling to experience the beauty, justice, and fairness of Muslim succession law.

Important considerations using calculators

Few important points to remember regarding Islamic Inheritance law and calculators.​

• Four Islamic inheritance law sources (Holy Quran, Sunnah, Ijma, and Qiyas) account for calculations.

• Calculations for Radd and Awwal are applied based on the total share. If the total share is more than one, all shares must be proportionally reduced (i.e., Awwal doctrine). If the total share is less than one and the residuary does not survive, all shares must be proportionally increased (i.e., Radd doctrine).

• The final Islamic inheritance shares must account for after deducting debts (loans, mortgages, etc.), expenses (burial cost, administration for executors and trustees, legal expenses), obligatory religious debts, taxes, and testamentary bequests (Al-wasiyyah).

• Not all calculators are the same, and the methodology may differ from one another to some extent.

• Calculators may be prone to errors due to relying on computer programming codes. It is strongly recommended to verify the result with knowledgeable Islamic scholars if you want to utilize it from an estate planning point of view, for example, during Probate processing or Trust settlements before estate distributions.

• Most calculators incorporate shares for fixed or prescribed sharers (Ashab al-Furudh) and Residuary (al-Asabat).

• Most calculators display the results in fractions, percentages (%), or both.

• No calculator on the web provides calculations for Distant kindred (Dhawul Arham). There are four classes of Distant kindred.

• Some of the calculators incorporate the Islamic jurisprudence (i.e., Hanafi, Shafii, Maliki, and Hanbali) differences of opinions.

• Calculators do not require prior knowledge and can be used by individuals, lawyers, judges, or scholars for learning purposes.

• Wassiyyah did not verify any errors or mistakes in the calculators.​
