This is a troop entering with you (in Hell), no welcome for them! Verily, they shall enter in the Fire!Here Allah tells us what the people of Hell will say to one another.This is like the Ayah:كُلَّمَا دَخَلَتْ أُمَّةٌ لَّعَنَتْ أُخْتَهَاEvery time a new nation enters, it curses its sister nation (that went before), (7:38) which means, instead of greeting one another, they will curse one another, accuse one another of being liars and reject one another.When a new group arrives, the keepers of Hell will say, هَذَا فَوْجٌ مُّقْتَحِمٌ مَّعَكُمْ لَا مَرْحَبًا بِهِمْ إِنَّهُمْ صَالُوا النَّارِ (This is a troop entering with you (in Hell), no welcome for them! Verily, they shall enter in the Fire!),meaning, because they are of the people of Hell
