What is the ruling on secretly breaking one's fast in Ramadan with the intention of not praying?

Fasting Ramadan is obligatory upon every adult, resident, able-bodied Muslim. It is not permissible to break the fast except for a legitimate Shar’i (Islamic legal) excuse. Whoever breaks the fast without an excuse has committed a major sin that necessitates sincere repentance by making up the missed days, feeling remorse, and resolving not to repeat it. Prayer is greater than fasting and is the pillar of Islam. Neglecting it incurs a severe threat of punishment in Hell, and some scholars have ruled that one who abandons it is a disbeliever. Prayer is the first thing a servant will be held accountable for on the Day of Judgment, and it is obligatory to repent from abandoning and neglecting it, as it is a pillar of Islam. It is not permissible to be deficient in one obligation under the pretext of being deficient in another; rather, all obligations must be fulfilled.
