وَإِذَا سَمِعُوا۟ مَآ أُنزِلَ إِلَى ٱلرَّسُولِ تَرَىٰٓ أَعْيُنَهُمْ تَفِيضُ مِنَ ٱلدَّمْعِ مِمَّا عَرَفُوا۟ مِنَ ٱلْحَقِّ ۖ يَقُولُونَ رَبَّنَآ ءَامَنَّا فَٱكْتُبْنَا مَعَ ٱلشَّٰهِدِينَ
When they listen to that which hath been revealed unto the messengers, thou seest their eyes overflow with tears because of their recognition of the Truth. They say: Our Lord, we believe. Inscribe us as among the witnesses.
