وَهَٰذَا كِتَٰبٌ أَنزَلْنَٰهُ مُبَارَكٌ مُّصَدِّقُ ٱلَّذِى بَيْنَ يَدَيْهِ وَلِتُنذِرَ أُمَّ ٱلْقُرَىٰ وَمَنْ حَوْلَهَا … وَلَقَدْ جِئْتُمُونَا فُرَٰدَىٰ كَمَا خَلَقْنَٰكُمْ أَوَّلَ مَرَّةٍ
"This is a blessed Book We have sent down, confirming what came before it… And you have come to Us one by one, just as We created you the first time."
Muṣaddiqu'lladhī bayna yadayh — treated at Fāṭir 35/31 and al-Aḥqāf 46/12; umm al-qurā — treated at al-Shūrā 42/7. I rely on that treatment.
وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ قَالَ أُوحِىَ إِلَىَّ وَلَمْ يُوحَ إِلَيْهِ شَىْءٌ (93) — the pattern occurs for the second time in this sūra (21, 93). And the two alternatives here are worth recording: inventing a lie, and saying that revelation has come.
وَلَقَدْ جِئْتُمُونَا فُرَٰدَىٰ كَمَا خَلَقْنَٰكُمْ أَوَّلَ مَرَّةٍ وَتَرَكْتُم مَّا خَوَّلْنَٰكُمْ وَرَآءَ ظُهُورِكُمْ (94)
Furādā (one by one) — treated at Maryam 19/95 (wa kulluhum ātīhi yawma'l-qiyāmati fardā); khawwalnākum — treated at al-Zumar 39/8 and 39/49 (khawwalahū niʿmatan), and it was recorded there: what is given is named not as property but as something given into one's keeping. I rely on that treatment.
And the expression warāʾa ẓuhūrikum (behind your backs) is worth recording: the things left behind remain on the unseen side. I give this as an observation: the last verse of the sūra (165) will say that what is given is an instrument of trial; this verse shows where that instrument is left.
