I regularly read and study the Quran and when I encounter verses that seem to be duplicates turn out to differ by a few Arabic letters, which result in a slightly different meaning. This is expected since Allah swtl would not waste words. However, the verses 59:1 and 61:1 are letter for letter, exactly the same. Why is this? Other than the Bismillahs at the beginnings of each surah (except Tawbah), this is the only exact duplication I have seen.
Sabbaĥa Lillāh Mā Fī As-Samāwāti Wa Mā Fī Al-'Arđi ۖ Wa Huwa Al-`Azīzu Al-Ĥakīmu 061.001 Whatever is in the heavens and on earth, let it declare the Praises and Glory of God: for He is the Exalted in Might, the Wise. سَبَّحَ لِلَّهِ مَا فِي السَّمَاوَاتِ وَمَا فِي الأَرْضِ ۖ وَهُوَ الْعَزِيزُالْحَكِيمُ
