The word(s) "assembling" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) And thus We have inspired in thee a Lecture in Arabic, that thou mayst warn the mother-town and those around it, and mayst warn of a day of assembling whereof there is no doubt. A host will be in the Garden, and a host of them in the Flame.

(2) The day when He shall gather you unto the Day of assembling, that will be a day of mutual disillusion. And whoso believeth in Allah and doeth right, He will remit from him his evil deeds and will bring him unto Gardens underneath which rivers flow, therein to abide for ever. That is the supreme triumph.
