The Mawarith program prompts the user with questions about heirs and then displays the percentage shares of each heir of the estate.
The author distributes the program as a Windows CAB file. The CAB archive contains an installer and a readme file with further help on installation. You will need to unpack the archive first. There are many ways to unpack a CAB file, such as WinRAR.
The Mawarith program is a Windows program developed by Siraj Eruvadi.
The author wants this program to be a free Islamic software which people can copy and distribute at no cost. It is not to be sold.
For my research, I have checked this software to know whether it's reliable or not. Examining it with some combinations of heirs, I could understand that there is error in it. So, my research has concluded that it's not a reliable one for shareea law. It would be a great mission if all errors were corrected.
