Tafsir al-Jalalain                                                                                                                        تفسیر الجلالین                                                

{كَلَّا} لَا تَفْعَل مِثْل ذَلِكَ {إِنَّهَا} أَيْ السُّورَة أَوْ الْآيَات {تَذْكِرَة} عِظَة لِلْخَلْقِ

No indeed!, do not behave like this. Truly it, the Surah, is, or the verses [are], a reminder, an admonition for the entire creation

{فَمَنْ شَاءَ ذَكَرَهُ} حَفِظَ ذَلِكَ فَاتَّعَظَ بِهِ

So let whoever will, remember it, preserve it [in his memory] and thus be admonished by it

{فِي صُحُف مُكَرَّمَة} عِنْد اللَّه

On leaves [that are] honoured, by Allah

{مَرْفُوعَة} فِي السَّمَاء {مُطَهَّرَة} مُنَزَّهَة عَنْ مَسّ الشياطين

Elevated, in the heavens, purified, exalted above the touch of devils,

{بِأَيْدِي سَفَرَة} كَتَبَة يَنْسَخُونَهَا مِنْ اللَّوْح الْمَحْفُوظ

In the hands of scribes, who write it down from the Preserved Tablet,

{كِرَام بَرَرَة} مُطِيعِينَ لِلَّهِ تَعَالَى وَهُمْ الْمَلَائِكَة

Noble, pious, obedient to Allah, exalted be He: these being the angels.
