How can zinaa be proven?

I know that in the past if someone has committed adultery, they had to bring 4 witnesses .
My question is can we prove that today by using latest scientific methods as the DNA test, instead of bringing 4 witnesses.

Praise be to Allaah.

According to Islamic sharee’ah, zinaa can only be proven by clear evidence, namely the testimony of four trustworthy and sound witnesses who saw it actually happen, or by confession of guilt, or by the woman becoming pregnant. It cannot be proven by DNA testing or by use of cameras and videos in place of the things mentioned above. And Allaah knows best.
