Shariah/Ethical Compliant Investment

The own research allows for laymen like myself to use their own judgement to purchase srocks, which, could actually be non compliant and result in disallowed income. The scholars are not taking a stance and giving a difinitive list of halal stocks, which is why these apps have appeared.

The app I’m referring to which screens UK stocks is called Islamic investor that says Gregg’s is compliant. There others out there like it, which are even worse tbh.

Zoya says Tesla is Sharia compliant, how can this be when Tesla provide finance options on the purchase of their vehicles which includes interest. Interest is disallowed, so how can the stock be compliant?

Regarding the jurists who accept a small portions that are disallowed, would they intercede for us?
