Does looking at the pictures of semi-nude women in newspapers break wudhu?

Answer

While wudhu will physically not be nullified, it will be utterly destroyed spiritually. It is haraam to look at such evil pictures. The spiritual effect of wudhu is ruined, and the soul is tarnished. It is best to renew wudhu, and making Taubah (repenting) is Waajib. One of the fundamental conditions of Taubah is to pledge to Allah Ta'ala not to revert to the sin.
