«اِلْعُرُوقْ تِجْمَعْ بَعْضَهَا»

People who spring from the same origin tend to find one another and stay together. Shared descent, upbringing, or underlying nature works like a hidden thread, pulling kindred people into easy agreement and companionship without any deliberate effort. The key word also means veins and, figuratively, lineage, so the image is of shared stock, not plant roots alone.

The observation applies to good and bad alike. Honorable people gravitate toward honorable company, and those of base character settle among their own. The phrase can therefore celebrate loyalty among kin or quietly criticize a group bound by shared faults.

Use it when people of common background, family line, or temperament are seen keeping together, either to warmly acknowledge a natural bond or to remark wryly that disreputable people have found their own kind. Tone comes from context.
