وَٱلَّذِينَ يُؤْمِنُونَ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ وَبِٱلْـَٔاخِرَةِ هُمْ يُوقِنُونَ ﴿٤﴾
And who believe in what has been revealed to you, [O Muḥammad], and what was revealed before you, and of the Hereafter they are certain [in faith].
أُو۟لَـٰٓئِكَ عَلَىٰ هُدًۭى مِّن رَّبِّهِمْ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ ﴿٥﴾
Those are upon [right] guidance from their Lord, and it is those who are the successful.
إِنَّ ٱلَّذِينَ كَفَرُوا۟ سَوَآءٌ عَلَيْهِمْ ءَأَنذَرْتَهُمْ أَمْ لَمْ تُنذِرْهُمْ لَا يُؤْمِنُونَ ﴿٦﴾
Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.
خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَـٰرِهِمْ غِشَـٰوَةٌۭ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴿٧﴾
Allāh has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.
وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ وَبِٱلْيَوْمِ ٱلْـَٔاخِرِ وَمَا هُم بِمُؤْمِنِينَ ﴿٨﴾
And of the people are some who say, "We believe in Allāh and the Last Day," but they are not believers.
