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

(21) Those who disbelieve say: If only a portent were sent down upon him from his Lord! Say: Lo! Allah sendeth whom He will astray, and guideth unto Himself all who turn (unto Him),

(22) And verily We sent messengers (to mankind) before thee, and We appointed for them wives and offspring, and it was not (given) to any messenger that he should bring a portent save by Allah's leave. For everything there is a time prescribed.

(23) Lo! therein verily are portents for those who read the signs.

(24) Lo! therein is indeed a portent for believers.

(25) Therewith He causeth crops to grow for you, and the olive and the date-palm and grapes and all kinds of fruit. Lo! herein is indeed a portent for people who reflect.

(26) And He hath constrained the night and the day and the sun and the moon to be of service unto you, and the stars are made subservient by His command. Lo! herein indeed are portents for people who have sense.

(27) And whatsoever He hath created for you in the earth of divers hues, lo! therein is indeed a portent for people who take heed.

(28) Allah sendeth down water from the sky and therewith reviveth the earth after her death. Lo! herein is indeed a portent for a folk who hear.

(29) And of the fruits of the date-palm, and grapes, whence ye derive strong drink and (also) good nourishment. Lo! therein is indeed a portent for people who have sense.

(30) Then eat of all fruits, and follow the ways of thy Lord, made smooth (for thee). There cometh forth from their bellies a drink divers of hues, wherein is healing for mankind. Lo! herein is indeed a portent for people who reflect.
