Saadi book Gulistan of Sa'di
Alternative translation:
The children of Adam are limbs of a whole
Having been created of one essence.
When the calamity of time afflicts one limb
The other limbs cannot remain at rest.
If you have no sympathy for the troubles of others
You are not worthy to be called by the name of "man".
