Rasm dāris means a fading trace of a former dwelling; dāris qualifies the noun. The commentary also records meanings of muʿawwal connected with reliance or support, and with audible lamentation. In this context, the question points toward the absence of reliable solace.
Fa-hal ʿinda rasmin dārisin min muʿawwal is not a neutral request for information. The poet knows that the fading trace cannot bring back the beloved. The question thus operates as rhetorical denial, expressing helplessness more forcefully than a flat statement.
The six opening verses form one movement: a request to stop, locating the site, observing its traces, recalling departure, hearing companions' advice, and recognizing the limits of consolation.
