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

(1) And We said: Smite him with some of it. Thus Allah bringeth the dead to life and showeth you His portents so that ye may understand.

(2) And even if thou broughtest unto those who have received the Scripture all kinds of portents, they would not follow thy qiblah, nor canst thou be a follower of their qiblah; nor are some of them followers of the qiblah of others. And if thou shouldst follow their desires after the knowledge which hath come unto thee, then surely wert thou of the evil-doers.

(3) These are the portents of Allah which We recite unto thee (Muhammad) with truth, and lo! thou art of the number of (Our) messengers;

(4) And will make him a messenger unto the Children of Israel, (saying): Lo! I come unto you with a sign from your Lord. Lo! I fashion for you out of clay the likeness of a bird, and I breathe into it and it is a bird, by Allah's leave. I heal him who was born blind, and the leper, and I raise the dead, by Allah's leave. And I announce unto you what ye eat and what ye store up in your houses. Lo! herein verily is a portent for you, if ye are to be believers.

(5) And if their aversion is grievous unto thee, then, if thou canst, seek a way down into the earth or a ladder unto the sky that thou mayst bring unto them a portent (to convince them all)! - If Allah willed, He could have brought them all together to the guidance - So be not thou among the foolish ones.

(6) They say: Why hath no portent been sent down upon him from his Lord? Say: Lo! Allah is Able to send down a portent. But most of them know not.

(7) Who is guilty of more wrong than he who forgeth a lie against Allah, or saith: I am inspired, when he is not inspired in aught; and who saith: I will reveal the like of that which Allah hath revealed? If thou couldst see, when the wrong-doers reach the pangs of death and the angels stretch their hands out (saying): Deliver up your souls. This day ye are awarded doom of degradation for that ye spake concerning Allah other than the truth, and used to scorn His portents.

(8) He it is Who sendeth down water from the sky, and therewith We bring forth buds of every kind; We bring forth the green blade from which We bring forth the thick-clustered grain; and from the date-palm, from the pollen thereof, spring pendant bunches; and (We bring forth) gardens of grapes, and the olive and the pomegranate, alike and unlike. Look upon the fruit thereof, when they bear fruit, and upon its ripening. Lo! herein verily are portents for a people who believe.

(9) And they swear a solemn oath by Allah that if there come unto them a portent they will believe therein. Say; portents are with Allah and (so is) that which telleth you that if such came unto them they would not believe.

(10) Wait they, indeed, for nothing less than that the angels should come unto them, or thy Lord should come, or there should come one of the portents from thy Lord? In the day when one of the portents from thy Lord cometh, its belief availeth naught a soul which theretofore believed not, nor in its belief earned good (by works). Say: Wait ye! Lo! We (too) are waiting.
