In the name of Allah, Most Gracious, Most Merciful.
Somebody asked a scholar once about how their parents were encouraging them to buy a house on interest otherwise they’d be poor.
So the scholar answered:
“Allah will never put the secret of success in something that Allah forbade or has made haram.”
So if anybody ever tells you that you’ll only become wealthy if you deal in interest (riba), then they have lied to you. They have lied to you out of ignorance or for whatever reason because Allah subhanahu wa ta’ala will never put success in something that Allah has made haram. If you do see some people being successful with it, they’re being set up and you’re being set up. Their success will be in the short-term with failure, sadness and loss in the long-term. It’s a test from Allah subhanahu wa ta’ala.
This applies to everything in life, money, relationships, health etc…
“Allah will never put the secret of success in something that Allah forbade or has made haram.”
