466.Hadhrat Abu bin Umar (Allah be pleased with him) narrates that Muhammad (peace be upon him) said: "Fasting and the Qu'ran will intercede on behalf of one on the Day of Qiyaamah. The Fast will proclaim: 'O Allah! I prevented him from eating at carnal desire. Therefore for my sake accept my intercession on his behalf.' The Qu'ran will proclaim: 'I prevented him from sleep. Therefore accept my intercession on his behalf.' The intercession of both will be accepted."
(Ahmad, Tibrani, Hakim).
