Tafsir al-Sadi - Abd al-Rahman al-Sadi’ - (780)

(13–14) “Indeed, those who say, ‘Our Lord is Allah,’ and then remain steadfast will have no fear, nor will they grieve. They are the inhabitants of Paradise, abiding therein forever as a reward for what they used to do.”

That is, those who acknowledge Allah as their Lord, testify to His oneness, and commit themselves to obeying Him

and persevere in doing so—remaining “steadfast” throughout their lives—“will have no fear” of any evil that lies ahead of them, “nor will they grieve” over what they have left behind.

“They are the inhabitants of Paradise”; that is, its people, who will remain there and neither desire to leave it nor seek anything in its place, “abiding therein forever as a reward for what they used to do”: their faith in Allah, which necessarily entailed the righteous deeds upon which they remained steadfast.

﴿١٣-١٤﴾ ﴿إِنَّ الَّذِينَ قَالُوا رَبُّنَا اللَّهُ ثُمَّ اسْتَقَامُوا فَلا خَوْفٌ عَلَيْهِمْ وَلا هُمْ يَحْزَنُونَ * أُولَئِكَ أَصْحَابُ الْجَنَّةِ خَالِدِينَ فِيهَا جَزَاءً بِمَا كَانُوا يَعْمَلُونَ﴾ أي: إن الذين أقروا بربهم وشهدوا له بالوحدانية والتزموا طاعته ⦗٧٨١⦘ وداموا على ذلك، و ﴿اسْتَقَامُوا﴾ مدة حياتهم ﴿فَلا خَوْفٌ عَلَيْهِمْ﴾ من كل شر أمامهم، ﴿وَلا هُمْ يَحْزَنُونَ﴾ على ما خلفوا وراءهم. ﴿أُولَئِكَ أَصْحَابُ الْجَنَّةِ﴾ أي: أهلها الملازمون لها الذين لا يبغون عنها حولا ولا يريدون بها بدلا ﴿خَالِدِينَ فِيهَا جَزَاءً بِمَا كَانُوا يَعْمَلُونَ﴾ من الإيمان بالله المقتضى للأعمال الصالحة التي استقاموا عليها.
