The language and narrative of the Quran is deliberately left with gaps, so that the reader can actively participate in its comprehension through sound inferences and harmless imagination. Thus, not only is "unnecessary" repetition avoided, but the brain of the reader is stimulated. The Quran does not like a passive reader, and a lazy reader does not enjoy the Quran either. For other examples of scene overlaps, see 12:83; 26:16-18.
