Caution: Translations of Quran and Ḥadīth may lead to possible misapplications and misinterpretations. This site is intended for students of sacred knowledge that are proficient in comprehending classical Arabic and have a strong foundation in Islamic sciences.

quran:21:104 –

The Day when We will fold the heaven like the folding of a ˹written˺ sheet for the records. As We began the first creation, We will repeat it. ˹That is˺ a promise binding upon Us. Indeed, We will do it.  

The day (yawma is in the accusative because of an implied preceding udhkur, ‘mention’) when We shall roll up the heaven as the Scribe, ˹al-sijill being˺ the name of an angel, rolls up the written scroll, that is, the scroll of the son of Adam when he dies (the lām ˹of li’l-kitāb˺ is extra; alternatively, ˹one may read the verse so that˺ al-sijill is ‘the scroll’, and al-kitāb means al-maktūb ‘what is written’, in which case the lām ˹of li’lkitāb˺ has the sense of ˹the particle˺ ‘alā, ‘over’; a variant reading ˹for li’l-kitāb˺ has the plural, li’l-kutub, ‘the books’). As We began the first creation, from non-existence, We shall repeat it, after making it non-existent (the kāf ˹of ka-mā, ‘as’˺ is semantically connected to nu‘īdu, ‘We shall repeat ˹it˺’, and its ˹suffixed˺ pronoun ˹-hu, ‘it’˺ refers back to awwala, ‘the first’; the mā relates to the verbal noun) — a promise binding on Us (wa‘dan is in the accusative because ˹it is the direct object˺ of an implied preceding wa‘adnā, ‘We promised’, and ˹the clause˺ constitutes a confirmation of the import of the preceding ˹verse, 103˺). Truly We shall do ˹that˺, which We have promised.
القرآن:٢١:١٠٤ –

يَوْمَ نَطْوِي السَّمَاءَ كَطَيِّ السِّجِلِّ لِلْكُتُبِ ۚ كَمَا بَدَأْنَا أَوَّلَ خَلْقٍ نُعِيدُهُ ۚ وَعْدًا عَلَيْنَا ۚ إِنَّا كُنَّا فَاعِلِينَ  

{يوم} منصوب باذكر مقدراً قبله {نطوي السماء كطي السجل} اسم ملك {للكتاب} صحيفة ابن آدم عند موته واللام زائدة أو السجل الصحيفة والكتاب بمعنى المكتوب واللام بمعنى على وفي قراءة للكتب جمعاً {كما بدأنا أول خلق} من عدم {نُعيده} بعد إعدامه فالكاف متعلقة بنعيد وضميره عائد إلى أول وما مصدرية {وعداً علينا} منصوب بوعدنا مقدراً قبله وهو مؤكد لمضمون ما قبله {إنا كنا فاعلين} ما وعدناه.
