Quran 5:83 from Surah Al-Maaida on Divine Marvels.
وَإِذَا سَمِعُواْ مَآ أُنزِلَ إِلَى ٱلرَّسُولِ تَرَىٰٓ أَعۡيُنَهُمۡ تَفِيضُ مِنَ ٱلدَّمۡعِ مِمَّا عَرَفُواْ مِنَ ٱلۡحَقِّۖ يَقُولُونَ رَبَّنَآ ءَامَنَّا فَٱكۡتُبۡنَا مَعَ ٱلشَّٰهِدِينَ
English translation: And when they listen (to) what has been revealed to the Messenger you see their eyes overflowing with the tears for what they recognized of the truth They say Our Lord we have believed so write us with the witnesses
Transliteration: wa-idha sami'u ma unzila ila al-rasuli tara a'yunahum tafidu mina al-dam'i mimma arafu mina al-haqi yaquluna rabbana amanna fa-uk'tub'na ma'a al-shahidina
