Oh yeh.<quoted text>
The principle of reciprocity is found in all of the world's religions and ethical codes, both ancient and modern. Many are state in the negative, i.e., do not to others what you would not have them do to you. Others are positive--treat others as you would have them treat you. Some teachers, Christ among them, expected more of people, i.e, going the extra mile, turning the other cheek, giving the cloak to the one who steals your coat.
I raise proactivity to the level or principle:
The most noble of human attributes are kindness, empathy, and generosity. Embracing them brings happiness, rejecting them leads to misery. Why suffer needlessly by making others suffer as well?
Find it for me in Islam.
