The way of Aadam (‘alaihis salaam) is that he did not justify his mistake. Justifying one’s wrong is extremely dangerous since it can even lead to one losing his imaan.
Nowadays, wrong is being repackaged and given another name in an effort to justify it. Hence, Islamic terms are being used to legalise insurance and other interest based transactions.
When the disbelievers objected to the impermissibility of usury by saying that “Usury is just like trade”, Allah Ta‘ala did not even show them the difference between the two, rather He merely said: “Allah Ta‘ala has made trade permissible and usury impermissible,” thereby making it clear that both are totally different.
