«اخْتَلَسْنَا اللَّبْثَ وَلَمْ نُطِلِ الْمَكْثَ»
We snatched brief moments of rest and did not prolong our stay.
Ikhtalasa suggests snatching or taking something quickly. Here it makes rest seem like a moment stolen from the journey, rather than describing actual theft.
Labth / makth both refer to staying or remaining. In lam nuṭil, the negative particle lam governs the imperfect and negates past occurrence. Sound and grammar both underscore the brevity of each halt.
