Surah Al Ma'idah Tafseer

وَإِذَا سَمِعُواْ مَا أُنزِلَ إِلَى الرَّسُولِ تَرَى أَعْيُنَهُمْ تَفِيضُ مِنَ الدَّمْعِ مِمَّا عَرَفُواْ مِنَ الْحَقِّ

And when they listen to what has been sent down to the Messenger, you see their eyes overflowing with tears because of the truth they have recognized.

This refers to the good news that they have about the advent of Muhammad.

يَقُولُونَ رَبَّنَا امَنَّا فَاكْتُبْنَا مَعَ الشَّاهِدِينَ

They say:"Our Lord! We believe; so write us down among the witnesses."

who testify to the truth and believe in it.

وَمَا لَنَا لَا نُوْمِنُ بِاللّهِ وَمَا جَاءنَا مِنَ الْحَقِّ وَنَطْمَعُ أَن يُدْخِلَنَا رَبَّنَا مَعَ الْقَوْمِ الصَّالِحِينَ
