What is the meaning of the saying of the Messenger of Allah (peace and blessings be upon him): [I was not commanded to build up the mosques]?

Question:
Honorable Shaykh, may Allah grant you success, what is the meaning of the saying of the Messenger of Allah (peace and blessings be upon him) ?

Answer:
Yes, indeed. Building up means decorating them, constructing them, decorating them, and painting them. This is not permissible because it is disliked; that is, it is disliked because it distracts the worshippers and because there is no need for it. 'Umar (may Allah be pleased with him) said: "Build for the people what shelters them, and beware of making it red or yellow." We do not build up or boast. These are houses of worship, not houses of boasting or museums. No, they are houses of worship where strength and durability are fine, but there should be humility in the construction and in... Yes, do not occupy the people with that.
