«اِلْمِتْغَطِّي بِالْأَيَّامْ عِرْيَانْ»

The saying warns that leaning on good fortune gives no real shelter. Here "the days" means fortune and the run of circumstances, not calendar days. A person who treats a favorable period as a blanket against hardship only seems covered, because that comfort is borrowed from circumstances that will not stay.

Underneath is a view of time as unreliable and changeable. Prosperity can reverse without warning, so anyone whose security depends on luck alone stays exposed. The image of nakedness means being unprotected, not shame or indecency. Durable safety has to come from something steadier than the passing moment.

Use it to caution someone who leans on a current lucky streak, rising prosperity, or favorable conditions instead of building lasting security. It suits advice about saving, planning ahead, or not growing complacent during good times.
