Quran 2:137 from Surah Al-Baqara on Divine Marvels.
فَإِنۡ ءَامَنُواْ بِمِثۡلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهۡتَدَواْۖ وَّإِن تَوَلَّوۡاْ فَإِنَّمَا هُمۡ فِي شِقَاقٖۖ فَسَيَكۡفِيكَهُمُ ٱللَّهُۚ وَهُوَ ٱلسَّمِيعُ ٱلۡعَلِيمُ
English translation: So if they believe[d] in (the) like (of) what you have believed in [it] then indeed they are (rightly) guided But if they turn away then only they (are) in dissension So will suffice you against them Allah and He (is) the All-Hearing the All-Knowing
Transliteration: fa-in amanu bimith'li ma amantum bihi faqadi ih'tadaw wa-in tawallaw fa-innama hum fi shiqaqin fasayakfikahumu al-lahu wahuwa al-sami'u al-'alimu
