The word(s) "wast" appears 26 time(s) in 22 verse(s) in Quran in Muhammad Pickthal translation.

(11) (Saying): If ye do good, ye do good for your own souls, and if ye do evil, it is for them (in like manner). So, when the time for the second (of the judgments) came (We roused against you others of Our slaves) to ravage you, and to enter the Temple even as they entered it the first time, and to lay waste all that they conquered with an utter wasting.

(12) He said: So (it will be). Thy Lord saith: It is easy for Me, even as I created thee before, when thou wast naught.

(13) But the devil whispered to him, saying: O Adam! Shall I show thee the tree of immortality and power that wasteth not away?

(14) And thou didst that thy deed which thou didst, and thou wast one of the ingrates.

(15) And thou (Muhammad) wast not on the western side (of the Mount) when We expounded unto Moses the commandment, and thou wast not among those present;

(16) But We brought forth generations, and their lives dragged on for them. And thou wast not a dweller in Midian, reciting unto them Our revelations, but We kept sending (messengers to men).

(17) And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood.

(18) Lo! this in truth is Our provision, which will never waste away.

(19) (But now the answer will be): Nay, for My revelations came unto thee, but thou didst deny them and wast scornful and wast among the disbelievers.

(20) (Saying): Taste! Lo! thou wast forsooth the mighty, the noble!
