Al Qur'an, Sura Maryam, verse 58.
* It is reported that once 'Umar ibn al Khattab recited this chapter, prostrated himself at this point and remarked, "Here is the prostration but where is the crying?" (Ibn Jarir, Ibn Kathir).
* Ibn Majah, Ishaq ibn Rahuyah and Bazzaar have a report coming from Sa'd ibn Abi Waqqas. The Prophet(saws) said, "Recite the Qur'an and cry. If you cannot cry, then attempt to cry."(Alusi)
According to some scholars, the above report does not meet with strict conditions for acceptance. But Haythami expressed some confidence in it.
