Concise Quran Commentary
On the day the creation will hear the blast of the resurrection, in truth without any doubt. That day which they will hear it in is the day the dead will come out of their graves for the accounting and resurrection.
يَوْمَ يَسْمَعُونَ ٱلصَّيْحَةَ بِٱلْحَقِّ ۚ ذَٰلِكَ يَوْمُ ٱلْخُرُوجِ
the Day when they will hear the Blast [of the second Trumpet] in truth[21]. That is the Day of Resurrection.
