9:108
لَا تَقُمۡ فِيۡهِ اَبَدًاؕ لَمَسۡجِدٌ اُسِّسَ عَلَي التَّقۡوٰي مِنۡ اَوَّلِ يَوۡمٍ اَحَقُّ اَنۡ تَقُوۡمَ فِيۡهِؕ فِيۡهِ رِجَالٌ يُّحِبُّوۡنَ اَنۡ يَّتَطَهَّرُوۡاؕ وَاللّٰهُ يُحِبُّ الۡمُطَّهِّرِيۡنَ
Do not stand [for prayer] within it - ever. A mosque founded on righteousness from the first day is more worthy for you to stand in. Within it are men who love to purify themselves; and Allah loves those who purify themselves
