Ibn Zayd said: It is weathered trees that have crumbled away until the wind has scattered them (1). The meaning is that they became like dry trees when they are broken apart. The Arabs call anything that was once moist and then dries out dry debris.
Qatadah said: Like decayed, burned bones (2). Sa‘id ibn Jubayr said: It is the dust that crumbles away from a wall (3).
“And We have certainly made the Quran easy for remembrance; so is there anyone who will take heed? The people of Lot denied the warnings. Indeed, We sent against them a storm of stones, except for the family of Lot, whom We saved before dawn, as a favor from Us. Thus do We reward whoever is grateful.
