The Difference between Masjid At-Taqwa and Masjid Ad-Dirar

Allah the Exalted says that the Masjid that has been built on the basis of Taqwa of Allah and His pleasure is not the same as a Masjid that was been built based on causing harm, disbelief and causing division among the believers, and as an outpost for those who warred against Allah and His Messenger . The latter built their Masjid on the edge of a steep hole,

فِى نَارِ جَهَنَّمَ وَاللَّهُ لاَ يَهْدِى الْقَوْمَ الظَّـلِمِينَ

In the third (109) and the fourth (110) verses, Masjid Dirar (the harmful mosque) made by the hypocrites has been condemned as it has to be when compared with a masjid that is blessed. This has been accomplished through the use of a similitude. The surface of the land on which they were laying the foundation of their ` masjid' has been likened to a landmass that has been corroded on the inside by flowing water. The topsoil looks solid and smooth. Now, if someone starts building there, it is obvious that the whole thing would collapse instantly. Similarly, the foundation of this Masjid Dirar was inherently unstable. The result was that it collapsed and went right into the fire of Jahannam. The expression ` collapsed into the fire of Jahannam' could be figurative in its sense - in that it smoothed out the way of Jahannam for its makers. Some others have taken it in the real sense - in that the masjid, when made to collapse, went into the Jahannam. Allah knows best.
