(At-Thouba) 9 : 108
لَا تَقُمْ فِيهِ أَبَدًا ۚ لَمَسْجِدٌ أُسِّسَ عَلَى التَّقْوَىٰ مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَنْ تَقُومَ فِيهِ ۚ فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا ۚ وَاللَّهُ يُحِبُّ الْمُطَّهِّرِينَ

You don’t stand forever in it, a Masjid founded on heedfulness from the first day itself is worthier for you to stand in; in it are the men who love to purify themselves, and Allah loves those who like to purify themselves.

After one month of stay at Tabuk for defending Romans, Messenger and followers returned to Medina. This verse was revealed at that time. So, Messenger deputed a few of his companions to demolish the harmful Masjid Al-Dirar. “The Masjid founded on heedfulness from the first day itself” mentioned in this verse is about Masjid Al-Quba. It is told in verses 24: 35-37: “Allah, the Light of Heavens and earth, is present in the Masjids which He has permitted to be raised, wherein His name is to be remembered and to be glorified Him in the dusk and dawn. In it, there are men whose business neither diverts them from the remembrance of the Lord. They are regularly keeping up prayers, paying welfare-tax and fear a Day when hearts and eyes will be tremored”. 

It is told in verse 91: 8: “Each soul has given its wickedness and heedfulness; surely, the one who purifies the soul will be succeeded, and who fails to purify has corrupted his soul”. Adhikr which contains all previous 312 Books and their upright Explanations is the Book for Purification mentioned in verses 98: 2-3. It is told in verses 9: 28, 95 and 125 that the hypocrites and their Mushrik followers are filthy, and Adhikr will increase nothing but filth over filth for them. No one can make anyone a believer, but male or female by utilizing the Insight mentioned in verse 6: 104, Guidance mentioned in verse 17: 15 and the Truth mentioned in verses 10: 108 and 39: 41 can become a believer as explained in verse 2: 111. It is told in verses 56: 77-80: “Noble Reading Adhikr will not be grasped by none except by those who purified their soul with It”. See explanations 2: 152; 5: 6 and 9: 88.
