لَا تَقُمْ فِيهِ أَبَدًۭا ۚ لَّمَسْجِدٌ أُسِّسَ عَلَى ٱلتَّقْوَىٰ مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَن تَقُومَ فِيهِ ۚ فِيهِ رِجَالٌۭ يُحِبُّونَ أَن يَتَطَهَّرُوا۟ ۚ وَٱللَّهُ يُحِبُّ ٱلْمُطَّهِّرِينَ
Never stand (to pray) there. A place of worship which was found upon duty (to Allah) from the first day is more worthy that thou shouldst stand (to pray) therein, wherein are men who love to purify themselves. Allah loveth the purifiers.
Surah At-Tawba(9:108)
