O let my colleagues an upright running fast.

Fasting commanded by God in order to establish a righteous man. One notion is quite simple piety is carrying out God's commands and avoid prohibitions.
Thus, one definite indicator of the quality of one's fasting is obedience to God's command, including prayer.
A Muslim should not leave prayer under any circumstances, except for religion is justified, such as during menstruation or childbirth for women.
The threat of punishment from Allah and His Messenger are very hard on people who abandon or neglect the prayer (al-Maa'un [107]: 4-7).
In the hadith, "The agreement between us and them is prayer. Anyone who leaves the prayer then he is a disbeliever. "(Tirmidhi, Ahmad, Al-Nasai, and Ibn Majah).
Kafir is in this tradition is a great sin that is equivalent to the Gentiles who do not pray, not with a sense of meaning out of the infidels of Islam.
The daily prayers of Islam when the result came out with the denial of its obligations. However, if left as lazy or otherwise, to continue to believe he only obligation deemed committed great sins.
A Muslim must perform all required worship, including prayer, fasting, zakat, hajj, and others. As well, do not be picky in working, with working part and the other left.
God said, "Do you believe in the Book and disbelieve in part to some of the others?" (Surah al-Baqarah [2]: 85).
Every service has their provisions is a requirement and harmony, which has nothing to do with the terms and other religious harmony.
As long as someone has done a worship in accordance with the terms and rukunnya the legitimate worship and obligations tertunaikan though he sinned by leaving worship.
So, someone who is fast but not fast is valid because prayer is not mentioned conditions are valid fasting prayers. During fasting as applicable, ie not eating, not drinking, and did not have sex, and avoiding the things that cancel, then her fast is valid.
Only, he was a great sinner because of the daily prayers and must immediately repent. Regarding the reward of fasting, we fully submit to God.
To be sure, a person who fasts and prayers run a greater reward and a lot more than fast but do not pray. Wallahua'lam sowab bish.
