Repentance
[9:107]
And there are those who put up a mosque by way of mischief and infidelity - to disunite the Believers - and in preparation for one who warred against God and His Apostle aforetime. They will indeed swear that their intention is nothing but good; But God doth declare that they are certainly liars.


* v.107 : Three categories of Hypocrites having already been mentioned (n. 1354), a fourth class of insidious evil-doers is now mentioned, whose type is illustrated in the story of the Qubaa "Mosque of mischief (dhirar)". Qubaa is a suburb of Madinah about three miles to the south-east. When the Holy Prophet arrived at Madinah for Hijrat, he rested four days in Qubaa before entering the town of Madinah. Here was built the first mosque, the "Mosque of Piety" to which he frequently came during his subsequent stay in Madinah. Taking advantage of these sacred associations, some Hypocrites of the Tribe of Bani Ganam built an opposition mosque in Qubaa, pretending to advance Islam. In reality they were in league with a notorious enemy of Islam, one Abu ’Amir, who had fought against Islam at Uhud and who was now, after the battle of Hunain (A.H. 9), in Syria: his confederates wanted a mosque for him to come to, but it would only be a source of mischief and division, and the scheme was disapproved.
* Abu ’Amir, surnamed the Rahib (Monk), as he had been in touch with Christian monks. See last note.
