﴿ لَا تَقُمْ فِيهِ أَبَدًۭا ۚ لَّمَسْجِدٌ أُسِّسَ عَلَى ٱلتَّقْوَىٰ مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَن تَقُومَ فِيهِ ۚ فِيهِ رِجَالٌۭ يُحِبُّونَ أَن يَتَطَهَّرُوا۟ ۚ وَٱللَّهُ يُحِبُّ ٱلْمُطَّهِّرِينَ ﴾

“Never set foot in such a place! Only a house of worship founded, from the very first day, upon God-consciousness is worthy of thy setting foot therein -[a house of worship] wherein there are men desirous of growing in purity: for God loves all who purify themselves.”

There are two foundations for the building of life. One is piety (taqwa) and the other is self-centredness. In the first case the whole structure of life is built on a firm foundation of being God-fearing. In this case all the activities of the individual are influenced by one central thought. That is, he has to be accountable for all his words and deeds to a Being Who is aware of all things, whether open or hidden, and Who is to award punishments or rewards accordingly. One who considers himself accountable to God has erected his building on a solid foundation that will never be shaken. In contrast to him is the man who builds on the crumbling edge of an abyss. Free from all fears and apprehensions, he leads a self-oriented life in the world. He does not accept any restrictions, and speaks and acts at will. The example of the life of such a person can be compared to a building which has been constructed on the brink of a gorge which is about to cave in; all of a sudden it will collapse, carrying all the building’s residents down into its depths.
