﴿ إِنَّا سَنُلْقِى عَلَيْكَ قَوْلًۭا ثَقِيلًا ﴾

“Behold, We shall bestow upon thee a weighty message –”

(For We shall charge thee) for We shall send you Gabriel (with a word of weight) with mighty words containing commands and prohibitions, promises and threats, the lawful and unlawful; it is also said this means: with a tremendous word; and it is also said this means: a word that is heavy on whoever contravenes it; and it is also said this means: a weighty word in the prayer of the night.
