وَعَنْهُ قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُؤْتَى بِجَهَنَّمَ يَوْمَئِذٍ لَهَا سَبْعُونَ أَلْفَ زِمَامٍ مَعَ كُلِّ زِمَامٍ سَبْعُونَ أَلْفَ مَلَكٍ يَجُرُّونَهَا (( رَوَاهُ مُسْلِم)).
Ibn Mas'ud (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "Hell will be brought on that Day (the Day of Resurrection) with seventy thousand bridles; and with every bridle will be seventy thousand angels, pulling it". [Muslim].
