Hadith About Killing Homosexuals
here i will mention that if they conceal their sins and donot publicize it then in my opinion there will be no punishment other than lashes if found out as per Quran directives If they publicize or promote things,then it may be considered as fitna or fisaad which may come under death penalty as per Quran. In Ghamdi sb book Burhan, there is discussion about rajam, i think context can be applied in this case too.
The talk around 19 min implies that out side your marriage sexual relations are zina. And marriage is between male and female, so i inferred homosexuality will be cosnidered zina, isnt it? @UmerQureshi sb
