فَرِحِينَ بِمَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ وَيَسْتَبْشِرُونَ بِٱلَّذِينَ لَمْ يَلْحَقُوا۟ بِهِم مِّنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Jubilant (are they) because of that which Allah hath bestowed upon them of His bounty, rejoicing for the sake of those who have not joined them but are left behind: That there shall no fear come upon them neither shall they grieve.
