At Tawbah Ayah 108

لَا تَقُمْ فِيهِ أَبَدًا‌ۚ لَّمَسْجِدٌ أُسِّسَ عَلَى ٱلتَّقْوَىٰ مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَن تَقُومَ فِيهِ‌ۚ فِيهِ رِجَالٌ يُحِبُّونَ أَن يَتَطَهَّرُواْ‌ۚ وَٱللَّهُ يُحِبُّ ٱلْمُطَّهِّرِينَ ١٠٨ Do not ?O Prophet? ever pray in it. Certainly, a mosque founded on righteousness from the first day is more worthy of your prayers. In it are men who love to be purified. And Allah loves those who purify themselves.
