Deplete

The triliteral root nūn fā dāl (ن ف د) occurs in the Quran 5 times.

(18:109) Say, "If the sea were an inkwell for the words of my Lord, then the sea would run out (Arab. لَنَفِدَ, lanafida) before the words of my Lord run out (Arab. تَنْفَدَ, tanfada);" even if We were to bring another like it for its aid.

(31:27) If all the trees on the earth were made into pens, and the sea (of ink) were supplied by seven more seas, words of God would not run out (Arab. نَفِدَتْ, nafidat). God is Noble, Wise.
