What is the ruling on teaching how to calculate the surplus of usurious loans?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
"The intention behind teaching this subject should be considered. If it is for the benefit of usurious banks, companies, or individuals, then it is not permissible, as it involves assisting in usury. However, if it is solely for the purpose of knowledge or comparison, and no prohibitions result from it, then there is no harm."
