The word(s) "ya'juj" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) They said: "O Dhul-Qarnain! Verily ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?"

(2) So they [ya'juj and Ma'juj (Gog and Magog)] could not scale it or dig through it.

(3) And on that Day [i.e. the Day ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another; and the Trumpet will be blown, and We shall collect them (the creatures) all together.

(4) Until, when ya'juj and Ma'juj (Gog and Magog) are let loose (from their barrier), and they swoop down from every mound.
