وَإِذَا سَمِعُوا مَا أُنزِلَ إِلَى الرَّسُولِ تَرَىٰ أَعْيُنَهُمْ تَفِيضُ مِنَ الدَّمْعِ مِمَّا عَرَفُوا مِنَ الْحَقِّ ۖ يَقُولُونَ رَبَّنَا آمَنَّا فَاكْتُبْنَا مَعَ الشَّاهِدِينَ ٨٣

And (that is the reason) when (some of the true Christians) listen to this (Holy Qur’an) which has been revealed to the Messenger (blessings and peace be upon him), you see their eyes overflowing with tears. (This overflowing of tears) springs from the truth of which they have (gained) gnosis. (Besides) they submit: ‘O our Lord! We have believed (in the Truth which You have revealed), so inscribe us (also) amongst those who bear witness (to the truth). (5:83)
