bro. I m not implying to carry out rajm in a non-shariah based state. But just because people reject Riba, bro we should reject rajm? You say Riba is the root cause of many problems, isn't Zina a major cause of problems in our present society? Yesterday people rejected riba, today people want to reject rajm, tomorrow something else. Bro do you know a person who is stoned to death is actually experiencing a HUGE MERCY of Allah Ta'ala. It is a valid opinion that after the hadd punishment that person is NO LONGER held account for that sin in the AKHIRAH. Compare stoning to death to the dreaded punishment in Jahannam....! We should understand the hikmah of the laws of shariah in our mind bro. Allahu alam.
