The IRTH program is based on the book "Fiqh-us-Sunna" by Assayyed Sabeq. It was tested against over 160 cases, among which are all the cases listed in the ISNA booklet "Last Will and Testament". Also tested are the famous Shafii, Shuraih, Ali, Omar and Abu-Bakr challenges.
You are welcome to copy and distribute the source code of this program to as many people as you like at no cost. It is not to be sold.
The IRTH program calculates inheritance portions due to heirs according to Islamic Law. The program screen displays heir categories, e.g., sons, daughters, ...etc. Simply, enter the number of heirs in each category in the two columns labeled "Number of heirs". If there are no heirs in a given category, enter 0 or leave the category blank. When the last category is entered, click the button labeled "Calculate". The portions due each of the heirs will be displayed in a new window. If you want to donate a part of your estate, not to exceed a third of it, to a person who is not an eligible heir, you can do so by clicking on "Preferences", and typing the bequest as a fraction of the estate, e.g., 1/4, before you click on "Calculate". The preferences section also allows you to specify your preferred juristic school.
The program was successfully tested using Internet Explorer versions 5.5 and 6.0, Netscape Navigator versions 6.2 through 7.1, Mozilla version 1.4, America Online versions 6.0 through 9.0 and Firefox. It does not run under Netscape Navigator versions 4.5 or earlier, nor the Opera browser. I recommend Internet Explorer v4.0 or above.
