Is someone considered a disbeliever who prays once, twice, or three times a day, while believing in the articles of faith, paying zakat, and fasting Ramadan, but finds difficulty in performing all five daily prayers completely due to demanding work circumstances?

Allah has mandated five prayers a day and night, and commanded their preservation, establishment, and performance with humility, making them a means to success.

Prayer does not fall away from the accountable person as long as they are alive and of sound mind. Allah has made it easy by permitting combining and shortening prayers during travel, combining them in residence due to hardship, and praying according to one's ability for the sick.

Being busy with earning a livelihood is not an excuse for abandoning prayer. However, in cases of extraordinary hardship, combining prayers is permissible. A Muslim should perform the five prayers at their prescribed times and with the congregation, as this is a means to attain Allah's mercy and facilitate sustenance.

The questioner's assumption that he does not receive a salary for his prayers like imams is incorrect. Imams do not receive salaries for performing prayers; rather, they are compensated for dedicating their time to the duties of imamate and delivering sermons.

Family and children are not an excuse for abandoning some prayers, as the prayer time is short. Abandoning prayer for livelihood does not definitively constitute disbelief, but it is a major sin. The Fajr prayer must be performed at its prescribed time.
