Sheikh Khalid Yasin said Zina is not only the Haram sexual relationship, it's actually more than that! Prophet Muhammad (salaAllahu alaihi wa sallam) said:"The fornication of the two eyes is an evil glance. The fornication of the two ears is the obscene talk. The fornication of the tongue and hand is the touch and grasp. And the fornication of... the two feet is the steps taken towards evil. The heart desires and longs and the private parts abide with or does contrary to it”. (Mishkat ul Masabih, Abu Dawood)

so you must know that looking at opposite gender with lust, either in pictures, images, at colleges or at work, watching pornography or other indecent acts either openly or in the privacy of the home or on the internet is ALL forbidden..!

Ok, it is a good reminder.

okay.

I want to talk about that of the mouth. This happens when you have a 'fiance or fiancee' and or bf/gf with the thoughts that he is after all yours. People should be careful of falling into sins by talking 'too much'

ANyhow sha, it holds when between a man and a woman. and doesn't include lectures, e.t.c with the aim of acquiring knowledge

You are right
