Chapter: The saying of the listener to the reciter: “Enough!”
Narrated `Abdullah bin Mas`ud:
The Prophet (ﷺ) said to me, "Recite (the Qur'an) to me." I said, "O Allah's Messenger (ﷺ) Shall I recite (the Qur'an) to you while it has been revealed to you?" He said, "Yes." So I recited Surat-An-Nisa' (The Women), but when I recited the Verse: 'How (will it be) then when We bring from each nation a witness and We bring you (O Muhammad) as a witness against these people.' (4.41) He said, "Enough for the present," I looked at him and behold! His eyes were overflowing with tears
