Quran 27:92 from Surah An-Naml on Divine Marvels.
وَأَنۡ أَتۡلُوَاْ ٱلۡقُرۡءَانَۖ فَمَنِ ٱهۡتَدَىٰ فَإِنَّمَا يَهۡتَدِي لِنَفۡسِهِۦۖ وَمَن ضَلَّ فَقُلۡ إِنَّمَآ أَنَا۠ مِنَ ٱلۡمُنذِرِينَ
English translation: And that I recite the Quran And whoever accepts guidance then only he accepts guidance for himself and whoever goes astray then say Only I am of the warners
Transliteration: wa-an atluwa al-qur'ana famani ih'tada fa-innama yahtadi linafsihi waman dalla faqul innama ana mina al-mundhirina
