Touching hands and face. And letting nonharam touch your hand and face. Touching his hair or touching his arm..is this all included in zina?
Zina , that needs 4 witnesses and is punishable with "Hadd" punishment , is the penetration. Other than that : it Haram , and it's degree of 'Haram' differs from one action to another. They are called : "things that lead to Zina" , which are for example : touching with sexual lust(desire) , looking with sexual lust .. and so on.
and God knows best
