It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Prophet Muhammad (peace and blessings be upon him) said: "Fasting and the Qur'an will intercede for the servant. Fasting will say: My Lord! I kept him away from food and desires during the day, so accept my intercession for him. And the Qur'an will say: My Lord! I kept him away from sleep at night, so accept my intercession for him. Thus, both intercessions will be accepted."
