At-Tawbah 9:108

لَا تَقُمۡ فِيهِ أَبَدٗاۚ لَّمَسۡجِدٌ أُسِّسَ عَلَى ٱلتَّقۡوَىٰ مِنۡ أَوَّلِ يَوۡمٍ أَحَقُّ أَن تَقُومَ فِيهِۚ فِيهِ رِجَالٞ يُحِبُّونَ أَن يَتَطَهَّرُواْۚ وَٱللَّهُ يُحِبُّ ٱلۡمُطَّهِّرِينَ 108

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
