chins
in Edition Clear Qur'an by Talal Itani / Al-Israa (The Night Journey)

17:107Say, “Believe in it, or do not believe.” Those who were given knowledge before it, when it is recited to them, they fall to their chins, prostrating.

17:109And they fall to their chins, weeping, and it adds to their humility.
