I made a terrible mistake by trusting your promise, and spent the entire night waiting as if waiting for the Day of Judgment.

In this delightfully witty and dramatic couplet, the poet playfully laments his own foolishness for trusting the beloved's fickle word. The irony is brilliant: the beloved may have casually promised to meet on the Day of Reckoning (Qayamat) just to brush him off, and the hopelessly smitten lover spent the whole night actually waiting for the world to end just for that glimpse. It captures that quintessential, agonizing madness of romance, where the heart willingly believes a lie just to keep hoping.
