As-Sajdah · Al-Mulk

32:9 and 67:23 both list 'al-sam'a wa al-absar wa al-af'idah qalilan ma tashkurun' in almost identical wording — a four-surah cluster (16, 23, 32, 67) that forms one of the Quran's most repeated triad phrases.

Al-Qasas · As-Sajdah

Both describe the Quran's purpose as warning a people who received no warner before; 28:46 is embedded in the Moses narrative, 32:3 directly responds to the accusation that the Prophet invented the revelation.

Al-Furqan · As-Sajdah

Both open with 'who created the heavens, earth, and what is between them in six days then established Himself above the Throne'; 25:59 directs to ask one well-informed (al-Rahman), 32:4 emphasizes no intercessor without His leave.

Al-Mu'minun · As-Sajdah

23:78 and 32:9 both list the hearing-sight-hearts triad with the identical ending 'qalilan ma tashkurun' — the same gift acknowledged with the same blame for ingratitude.

Ta-Ha · As-Sajdah

Both ask 'does it not guide them how many We destroyed before them of nations whose dwellings they walk through?'; 20:128 opens with 'a-fa-lam' and 32:26 with 'a-wa-lam' -- the single letter change is the key difference.
