«قُلُوبْ عَلِيهَا دْرُوبْ وِقْلُوبْ مِنِ الْهَمِّ تْدُوبْ»

People differ sharply in how trouble reaches them. Some hearts seem shut behind a gate, drūb here meaning doors rather than paths, so sorrow knocks and cannot enter; others are so tender that even a small care wears them down until they seem to dissolve.

The saying places these two kinds of heart side by side, tied together by the Arabic rhyme of drūb and tdūb. It neither praises nor condemns either temperament; its point is that equal hardship does not produce equal suffering, because inner resilience varies.

Fits moments when one person shrugs off a misfortune that leaves another distraught. It can explain or soften the gap between their reactions, or remind listeners not to expect everyone to carry grief and worry in the same way.
