The World Federation One Stop Fiqh

Ruling 1011

The bending forward must be done with the intention of performing rukūʿ; therefore, if it is done with some other intention – for example, to kill an animal – then one cannot consider it as rukūʿ. Instead, he must stand up straight and then bend forward again for rukūʿ; by doing this, a rukn is not added and the prayer does not become invalid.
