إِنَّ ٱلَّذِينَ قَالُواْ رَبُّنَا ٱللَّهُ ثُمَّ ٱسۡتَقَٰمُواْ فَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ ١٣
Indeed, those who have said, "Our Lord is Allāh," and then remained on a right course - there will be no fear concerning them, nor will they grieve.
Translation: Saheeh International (English)
Each word's meaning and sound
Indeed, those who say, “Our Lord is Allah; we have no Lord besides Him”, then they become firm on faith and good actions, there will be no fear on them in what they face in the Hereafter, nor will they grieve over the fortune of this worlds which escaped them or what they left behind them.
