206 Lexical Explanation:
«يَتَبَاهَى » will boast to one another. «فِي اَلْمَسَاجِدِ» That is, in the height and grandeur of the mosque buildings, in their adornment, embellishment, and beauty; or it may mean that they will sit in the mosques and boast about their affairs, not respecting them. Rather, in the very place where prayer, recitation of the Qur’an, remembrance of Allah, etc., should take place, they will commit the vile act of pride and arrogance.

Benefit:
Near the Day of Judgment, a time will come when people will build mosques and adorn them with elaborate designs and decorations. Then they will compete with one another, saying, “Our mosque is more beautiful and better than so-and-so’s mosque.” However, they will not be populated; they will be empty of worshippers and will lament the indifference and lack of attention of those who built them.

Hafiz Muhammad Ameen
690. Commentary: Competing with one another in good deeds is recommended (mustahabb). Allah the Exalted says: «فَاسْتَبِقُوا الْخَيْرَاتِ» [البقرہ 148 : 2]
“Race with one another in good deeds and virtues.” In this regard, the construction of mosques is a commendable act and a sign of faith. However, in building mosques, only daily necessities should be taken into consideration—those which are genuine human needs and required by nature. That is, for protection against seasonal changes (such as storms, hurricanes, heat, and cold, etc.), the structures of mosques should be stable. But they should not be decorated and adorned excessively and unnecessarily in the manner of the synagogues and churches of the Jews and Christians. There is a severe prohibition of this in the ahadith. See: [سنن أبي داود ، الصلاۃ ، حدیث 428]
Furthermore, merely building mosques should not be the objective; rather, their primary purpose should be to populate and enliven them. Otherwise, if their construction is exaggerated solely for the sake of competition, pride, and boasting, then this is a sign of the nearness of the Hour (Qiyamah).

449. Commentary:
"Boasting about mosques" means that people will boast to one another regarding mosques, for example: our mosque is bigger, taller, more beautiful, etc. And it can also mean that instead of sitting in mosques to remember Allah, they will engage in boastful conversations. Both of these situations are very blameworthy.

Benefits and Issues:
(1)
The actions that have been described as signs of the nearness of the Hour are disliked, meaning these actions will be performed by those who are estranged from the true spirit of the religion and are unaware of the correct teachings of the religion.

(2)
Two meanings have been stated for pride in mosques:

* One is that, instead of being engaged in learning and teaching the religion, or in remembrance, recitation, and prayer, people will become occupied in such matters in the mosques in which they will express pride over abundance in wealth and similar things—something that should not even be done outside the mosque.

* The second meaning is that people will take pride in the construction of mosques. Their attention will be directed towards the outward grandeur and splendor of the mosques rather than towards populating the mosque and adhering to congregational prayer. Both of these actions are bad and it is necessary to avoid them.

Imam Ibn Majah rahimahullah, from the chapter heading under which he has mentioned this hadith, indicates that in his view, the second meaning of the hadith is more correct.

(3)
The title of the chapter is Tashid al-Masajid (Embellishing/Ornamenting the Mosques).
There are two meanings of this tashid:
One is constructing large and expansive buildings, as we see nowadays that mosques are built very spacious, the buildings are made tall and grand, but at the time of prayer, barely one or two rows are filled, whereas the real importance is that at every prayer time, all Muslims should come to the mosque to pray; then, if the need is felt, more space can be added to the mosque.
The second meaning of tashid is to plaster the building with lime and gypsum; in ancient times, this was the method to preserve the building.
Nowadays, better and better cement, steel, etc. are used, and the walls and roof are adorned with marble and tiles, whereas what is more needed is to strengthen faith (iman) and piety (taqwa), and to attend the mosques regularly. However, considering appropriate protective measures in construction according to local climatic conditions is not prohibited.
