Friend Needs Polish Translation

Hello, my friend sent this to me, but I don’t understand polish. Can you translate this to english? Thanks. Jeżeli f jest funkcją nieparzystą i całkowalną to Bóg mi świadkiem że całka na przedziale -a do a z f od x delta x jest równa zero Mariusz Pudzianowski

A Reddit post asks for a translation of a Polish image. The image shows muscular strongman Mariusz Pudzianowski beside a Polish statement of a basic calculus rule: the integral of an odd function over a symmetric interval equals zero. The joke is that the supposedly mysterious Polish message is an intimidating-looking math fact attributed to a very imposing man, used when someone asks for help translating or deciphering something.
