Why are the conditions for prayer complicated and numerous, and why is men's prayer invalidated if they pray in short clothes?

The nine conditions of prayer (Islam, sanity, discernment, entry of time, purity, covering the 'awrah, avoiding impurities, facing the Qiblah, and intention) are neither numerous nor complex. Some of them are naturally present, some are easy to fulfill and relate to cleanliness and elegance, and others are organizational. These conditions aim to extract the Muslim from worldly immersion and achieve tranquility, solemnity, and humility in worship, unlike the spontaneity that may exist in other religions and does not achieve the same effect.
