At-Tawba 9:107

There are those [hypocrites] who built a mosque to cause harm[80], promote disbelief and create division among the believers, and as a base for those who had previously fought against Allah and His Messenger. They will surely swear, “We intend nothing but good,” but Allah testifies that they are indeed liars.

[80] The most conniving hypocrites in Madinah built a mosque ‘masjid al-dirār’ (the mosque of harm) to cause dissension and discord among Muslims.

And [there are] those [hypocrites] who took for themselves a mosque for causing harm and disbelief and division among the believers and as a station for whoever had warred against Allāh and His Messenger before. And they will surely swear, "We intended only the best." And Allāh testifies that indeed they are liars.

107. And as for those who put up a mosque by way of harm and disbelief and to disunite the believers and as an outpost for those who warred against Allâh and His Messenger (Muhammad صلى الله عليه وسلم) aforetime, they will indeed swear that their intention is nothing but good. Allâh bears witness that they are certainly liars.

And as for those who chose a place of worship out of opposition and disbelief, and in order to cause dissent among the believers, and as an outpost for those who warred against Allah and His messenger aforetime, they will surely swear: We purposed naught save good. Allah beareth witness that they verily are liars.
