Said in the sixth verse (49) is: أَهَـٰؤُلَاءِ الَّذِينَ أَقْسَمْتُمْ لَا يَنَالُهُمُ اللَّـهُ بِرَحْمَةٍ ۚ ادْخُلُوا الْجَنَّةَ لَا خَوْفٌ عَلَيْكُمْ وَلَا أَنتُمْ تَحْزَنُونَ ﴿49﴾ (Is it these for whom you swore that Allah would not reach them with mercy?" - "Enter the Paradise; there is no fear on you, nor shall you grieve).
Explaining this, Sayyidna ` Abdullah ibn ` Abbas ؓ says: When the questions and answers between the people of A` raf and the people of Paradise and Hell both will be over, that will be the time when the Lord of all the worlds will address the people of Hell and tell them about the people of A` raf that they swore that the people of A` raf will not be forgiven their sins and mercy will not be shown to them. Then, there comes an immediate declaration of His mercy when the people of A` raf will be told: Go and enter the Paradise. You should have no fear of what had happened in the past nor should you have any anxiety about the future. (Ibn Kathir)
