This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions about comparative religion, and questions about what others have written about Judaism, are off-topic on Mi Yodeya. This includes any question that requires of its answerers any knowledge of a religion besides Judaism." – mevaqesh, sabbahillel, mbloch, Danny Schoemann, Gershon Gold
Ahimsa is from the Sanskrit for non-violence: Origin: Sans ahimsā, non-injury < a-, not + himsā, injury < IE *ĝheis-, to wound < base *ĝhei-, to hurl, projectile.
Hamsa is the Arabic for "five", and since the hand has five fingers (or four + a thumb, for the pedants), it is an obvious connection.
Now, the origin of the hamsa symbol is a whole other question which I have neither time nor space to answer here. Perhaps another time.
