Surah Al-Mai'dah (The Spread Table), Verse 83

وَاِذَا سَمِعُوْا مَاۤ اُنْزِلَ اِلَی الرَّسُوْلِ تَرٰۤی اَعْیُنَهُمْ تَفِیْضُ مِنَ الدَّمْعِ مِمَّا عَرَفُوْا مِنَ الْحَقِّ یَقُوْلُوْنَ رَبَّنَاۤ اٰمَنَّا فَاكْتُبْنَا مَعَ الشّٰهِدِیْنَ ۟

Wa izaa sami'oo maaa unzila ilar Rasooli taraaa a'yunahum tafeedu minad dam'i mimmmaa 'arafoo minalhaqq; yaqooloona Rabbanaaa aamannaa faktubnaa ma'ash shaahideen

“And when they listen to the revelation received by the Messenger, thou wilt see their eyes overflowing with tears, for they recognise the truth: they pray: "Our Lord! we believe; write us down among the witnesses.”
