«عُمْرِ الدَّم مَا يِبْقَى مَيَّهْ»

The proverb holds that a family bond cannot dissolve into nothing. However bitter a dispute between relatives becomes, the shared blood that ties them stays what it is. The opening عُمْر ... مَا simply means 'never' here, not anyone's age: blood never turns into water.

It also carries a hopeful forecast: kin who have fallen out will sooner or later come back together, because the tie between them outlasts any rift, anger, or period of estrangement.

Fits moments when relatives have quarreled or drifted apart and someone wants to predict, or encourage, their eventual reconciliation. It suits kin specifically, not friends or allies, and can soothe a family member nursing a grudge.
