A recurring Qur'anic theme is that wealth belongs to Allah first; a person is only its trustee (amanah) for a time, accountable for how it was earned and how it is used. This reframes money from a purely personal possession into something you will be asked about — where it came from and where it went.

Two commands anchor how that trust plays out in dealings with other people: fulfilling contracts and agreements in full, and never taking someone else's wealth through injustice, deception, or exploitation, only through fair trade by mutual consent.

Held together, these principles are why Islamic financial ethics keep returning to the same few questions: was this profit earned through real effort, risk, and value creation? Was the other party treated with full honesty? And is any obligation I've made being honoured?
