Quran 46:9 from Surah Al-Ahqaf on Divine Marvels.
قُلۡ مَا كُنتُ بِدۡعٗا مِّنَ ٱلرُّسُلِ وَمَآ أَدۡرِي مَا يُفۡعَلُ بِي وَلَا بِكُمۡۖ إِنۡ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَيَّ وَمَآ أَنَا۠ إِلَّا نَذِيرٞ مُّبِينٞ
English translation: Say Not I am a new (one) among the Messengers and not I know what will be done with me and not with you Not I follow but what is revealed to me and not I am but a warner clear
Transliteration: qul ma kuntu bid'an mina al-rusuli wama adri ma yuf'alu bi wala bikum in attabi'u illa ma yuha ilayya wama ana illa nadhirun mubinun
