Qur'an 69:7 · Al-Haaqqa

سَخَّرَهَا عَلَيْهِمْ سَبْعَ لَيَالٍۢ وَثَمَٰنِيَةَ أَيَّامٍ حُسُومًۭا فَتَرَى ٱلْقَوْمَ فِيهَا صَرْعَىٰ كَأَنَّهُمْ أَعْجَازُ نَخْلٍ خَاوِيَةٍۢ

(7) Which He [i.e., Allāh] imposed upon them for seven nights and eight days in succession, so you would see the people therein fallen as if they were hollow trunks of palm trees.
