«اِلْعَقْرَبَهْ أُخْتِ الْحَيَّهْ»

Two creatures known for their dangerous stings and bites are figuratively treated as siblings. The kinship marks likeness in harmfulness, not any real family tie: whatever small differences separate them, both bring the same pain to anyone who comes near, so neither can claim to be gentler than the other.

The speaker rejects an attempt to rank two offenders, rivals, or bad options as if one were clearly better. By insisting they are equally damaging, the saying ends the comparison and warns the listener not to trust either one.

Use it when someone argues that one of two troublesome people or options is the better choice, to say both cause equal harm and neither deserves preference. Said of real people, it brands both as harmful and can come across as an insult.
