I will create in them false desires and order them to slit the ears of cattle. I will order them to tamper with Allah’s creation.” Therefore, whoever takes Shaitan as a guardian instead of Allah, has indeed become a clear-cut loser.
Meaning:-
Slit: to cut apart or open along a line; make a long cut, fissure, or opening in.
Tamper: interfere with (something) in order to cause damage or make unauthorized alterations.
