Is a woman forbidden to shake hands with boys?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

Women are permitted to touch and shake hands with boys who are not sexually desired. This applies only to normal women whose nature is sound.  Otherwise, it is impermissible.

Allaah Knows best.
