And the Exalted informed that Paradise is only for the believers; so He said: "Yes, whoever submits his face to Allah," meaning: whoever makes his religion sincere for Allah, "and he is a doer of good," "for him is his reward," "and no fear will there be upon them nor will they grieve" over the world, the verse.
وَأخْبر تَعَالَى أَن الجَنَّة إِنَّمَا هِيَ للْمُؤْمِنين؛ فَقَالَ: ﴿بَلَى مَنْ أَسْلَمَ وَجهه لله﴾ أَي: أخْلص دينه لله ﴿وَهُوَ محسن﴾ ﴿فَلهُ أجره﴾ (وَلا خَوْفٌ عَلَيْهِمْ وَلَا هم يَحْزَنُونَ﴾ على الدُّنْيَا] الْآيَة.
[أَيَّة]
