Is it permissible to delay all prayers to perform them after returning home due to work circumstances?

Prayer is the greatest pillar of Islam after the Two Testimonies, and delaying it beyond its prescribed time is among the major sins. It must be performed on time. For one who finds this difficult, it is permissible to combine the two prayers that share a time (Dhuhr and Asr, Maghrib and Isha), either by performing the second early (taqdim) or delaying the first (ta'khir). However, delaying a daytime prayer until night or vice-versa, or combining prayers without need, is not permissible. A Muslim should be proud of his religion and perform prayer at its appointed time.
