Surah At-Tawbah, Verse 108

لَا تَقُمۡ فِيهِ أَبَدٗاۚ لَّمَسۡجِدٌ أُسِّسَ عَلَى ٱلتَّقۡوَىٰ مِنۡ أَوَّلِ يَوۡمٍ أَحَقُّ أَن تَقُومَ فِيهِۚ فِيهِ رِجَالٞ يُحِبُّونَ أَن يَتَطَهَّرُواْۚ وَٱللَّهُ يُحِبُّ ٱلۡمُطَّهِّرِينَ١٠٨

lā taqum fīhi abadan lamasjidun ussisa ʿalā l-taqwā min awwali yawmin aḥaqqu an taqūma fīhi fīhi rijālun yuḥibbūna an yataṭahharū wal-lahu yuḥibbu l-muṭahirīna

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 Allāh loves those who purify themselves.
