quran:79:27 –

Are you a more difficult creation or is the heaven? Allah constructed it.  

Are you (read a-antum pronouncing both hamzas, or by substituting an alif for the second one, not pronouncing it and inserting an alif between the one not pronounced and the former, or without ˹this insertion˺), namely, ˹you˺ the deniers of the Resurrection, harder to create or the heaven which He has built?, harder to create (banāhā: an explication of the manner of ˹its˺ creation).
القرآن:٧٩:٢٧ –

أَأَنْتُمْ أَشَدُّ خَلْقًا أَمِ السَّمَاءُ ۚ بَنَاهَا  

{أأنتم} بتحقيق الهمزتين وإبدال الثانية ألفاً وتسهيلها وإدخال ألف بين المسهلة والأخرى وتركه، أي منكرو البعث {أشد خلقا أم السماء} أشد خلقا {بناها} بيان لكيفية خلقها.
