Hadith on Mosques: The Day of Judgment will not come until people compete in decorating the Masajid

Anas reported: The Prophet, peace be upon him, said, “The Hour will not be established until the people compete with each other concerning the mosques.”

[Sunan Abu Dawud, Book of Prayer, Number 449, Sahih]

عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا تَقُومُ السَّاعَةُ حَتَّى يَتَبَاهَى النَّاسُ فِي الْمَسَاجِدِ
