(Al-Vaqia) 56 : 7
وَكُنْتُمْ أَزْوَاجًا ثَلَاثَةً
And you will be sorted in to three classes.
Even though as explained in verse 56: 3, those who received the Book of Lord are to be sorted into four classes, the Hypocrites who will go to the Hell even without trial are not considered in this verse since they have been killed by the Lord as told in verses 63: 4; and 80: 17. So they won’t be undergone for trial in this world. See explanation 33: 60-61; and 35: 32.
