Islam is a religion of simplicity and it encourages people to live humbly and spend honestly (without luxury) so is architecture a good profession according to Islām (as we play a vital role in shaping a country’s development)?

Architecture is a halāl [lawful] field and necessary for human habitation needs. The general legal rule pertaining to worldly matters: Everything is lawful until deemed unlawful. With Islamic principles in mind, one can serve the community and Allāh through this field.
