(Al-Muthwaffifeen) 83 : 34
فَالْيَوْمَ الَّذِينَ آمَنُوا مِنَ الْكُفَّارِ يَضْحَكُونَ
So, on that Day, the believers will be ridiculing the Kuffar.
The Kuffar mentioned in this verse, the Fujjar mentioned in verse 83: 7, and the Mujirims mentioned in verse 83: 29 are the same. They come only from the people of the Messenger who inherited the Lord’s Book, as explained in verse 35: 32. That Day mentioned here is the Day of Judgement. See explanation 7: 48–51; 37: 50–57; 48: 29; and 74: 38–47.
