It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that I began to recite from Surah An-Nisa in front of the Prophet (peace and blessings be upon him). When I reached this verse: «﴿فَكَيْفَإِذَاجِئْنَامِنْكُلِّأُمَّةٍبِشَهِيدٍوَجِئْنَابِكَعَلَىهَؤُلَاءِشَهِيدًا﴾ [النساء : 41]» "How will it be when We bring from every nation a witness, and We bring you as a witness over all of them?" the eyes of the Prophet (peace and blessings be upon him) began to shed tears.
