﴿ وَٱلْقَمَرَ قَدَّرْنَٰهُ مَنَازِلَ حَتَّىٰ عَادَ كَٱلْعُرْجُونِ ٱلْقَدِيمِ ﴾

“and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved:”

(And for the moon We have appointed mansions) like the mansions of the sun: it increases and decreases (till she return like an old shrivelled palm leaf.
