The word(s) "portent" appears 104 time(s) in 94 verse(s) in Quran in Muhammad Pickthal translation.

(11) And they said: Whatever portent thou bringest wherewith to bewitch us, we shall not put faith in thee.

(12) Lo! in the difference of day and night and all that Allah hath created in the heavens and the earth are portents, verily, for folk who ward off (evil).

(13) And they will say: If only a portent were sent down upon him from his Lord! Then say, (O Muhammad): The Unseen belongeth to Allah. So wait! Lo! I am waiting with you.

(14) He it is Who hath appointed for you the night that ye should rest therein and the day giving sight. Lo! herein verily are portents for a folk that heed.

(15) But this day We save thee in thy body that thou mayst be a portent for those after thee. Lo! most of mankind are heedless of Our portents.

(16) Lo! herein verily there is a portent for those who fear the doom of the Hereafter. That is a day unto which mankind will be gathered, and that is a day that will be witnessed.

(17) How many a portent is there in the heavens and the earth which they pass by with face averted!

(18) And He it is Who spread out the earth and placed therein firm hills and flowing streams, and of all fruits He placed therein two spouses (male and female). He covereth the night with the day. Lo! herein verily are portents for people who take thought.

(19) And in the Earth are neighbouring tracts, vineyards and ploughed lands, and date-palms, like and unlike, which are watered with one water. And we have made some of them to excel others in fruit. Lo! herein verily are portents for people who have sense.

(20) Those who disbelieve say: If only some portent were sent down upon him from his Lord! Thou art a warner only, and for every folk a guide.
