What is the wisdom behind the pilgrim in a state of ihram divesting himself of sewn garments during Hajj and Umrah?

The wisdom of detachment in Ihram is manifested in several aspects:

Firstly: Achieving complete humility before Allah Almighty, outwardly and inwardly, as the rich and the poor become equal in clothing.

Secondly: Demonstrating the unity of Muslims and that they are one nation in dress, as is evident in their circumambulation, standing, and stoning in unified places.

Thirdly: Reminding man that he will depart from this world in a shroud similar to this garment, not in luxurious clothes.
