[Pooya/Ali Commentary 77:7] These verses refer to the events that will happen on the day of resurrection. The prophets, sent in succession at different times to all nations, will be gathered together in one place before the seat of judgement to bear witness as to the righteous or the unjust among their followers and the Holy Prophet as a witness over all the prophets of Allah. See commentary of Bara-at: 105; Nisa: 41; Nahl: 89 and Baqarah: 143).
