Future events may also be presented through active or passive participles. These nominal forms can depict an assured future occurrence as a settled description rather than a merely anticipated action.
«وَإِنَّ الدِّينَ لَوَاقِعٌ»
Judgment will certainly take place. (Qurʾān 51:6)
«ذَٰلِكَ يَوْمٌ مَجْمُوعٌ لَهُ النَّاسُ»
That is a day for which people will be gathered. (Qurʾān 11:103)
«واقع» is an active participle and «مجموع» a passive participle. Both describe events associated with the future in terms that stress their assured realization.
Keep morphology and rhetoric distinct: the word pattern identifies the form, while the context explains its force of certainty.
