Fasting will act as And Intercessor
“`Abdullah ibn `Amr reported that the Messenger of Allah, (saw) said: ‘The fast and the Qur’an are two intercessors for the servant of Allah on the Day of Resurrection. The fast will say: ‘O Lord, I prevented him from his food and desires during the day. Let me intercede for him.’ The Qur’an will say: ‘I prevented him from sleeping at night. Let me intercede for him.’ And their intercession will be accepted’.” [Ahmad, al-Musnad, 10/118 and al-Haythami, Majma` al-Zawa’id, 3:184]:
الصيام والقرآن يشفعان للعبد يوم القيامة يقول الصيام أي رب منعته الطعام والشهوات بالنهار فشفعني فيه ويقول القرآن منعته النوم بالليل فشفعني فيه قال فيشفعان.
