وَالَّذِينَ اتَّخَذُواْ مَسْجِدًا ضِرَارًا وَكُفْرًا وَتَفْرِيقًا بَيْنَ الْمُؤْمِنِينَ وَإِرْصَادًا لِّمَنْ حَارَبَ اللَّهَ وَرَسُولَهُ مِن قَبْلُ وَلَيَحْلِفَنَّ إِنْ أَرَدْنَا إِلاَّ الْحُسْنَى وَاللَّهُ يَشْهَدُ إِنَّهُمْ لَكَـذِبُونَ - لاَ تَقُمْ فِيهِ أَبَدًا لَّمَسْجِدٌ أُسِّسَ عَلَى التَّقْوَى مِنْ أَوَّلِ يَوْمٍ أَحَقُّ أَن تَقُومَ فِيهِ فِيهِ رِجَالٌ يُحِبُّونَ أَن يَتَطَهَّرُواْ وَاللَّهُ يُحِبُّ الْمُطَّهِّرِينَ
107. And as for those who put up a Masjid by way of harm and disbelief and to disunite the believers and as an outpost for those who warred against Allah and His Messenger aforetime, they will indeed swear that their intention is nothing but good. Allah bears witness that they are certainly liars. 108. Never stand you therein. Verily, the Masjid whose foundation was laid from the first day on Taqwa is more worthy that you stand therein (to pray). In it are men who love to clean and purify themselves. And Allah loves those who make themselves clean and pure. The reason behind revealing these honorable Ayat is that before the Messenger of Allah migrated to Al-Madinah, there was a man from Al-Khazraj called â€Abu `Amir Ar-Rahib (the Monk).'' This man embraced Christianity before Islam and read the Scriptures. During the time of Jahiliyyah, Abu `Amir was known for being a worshipper and being a notable person among Al-Khazraj. When the Messenger of Allah arrived at Al-Madinah after the Hijrah, the Muslims gathered around him and the word of Islam was triumphant on the day of Badr, causing Abu `Amir, the cursed one, to choke on his own saliva and announce his enmity to Islam. He fled from Al-Madinah to the idolators of Quraysh in Makkah to support them in the war against the Messenger of Allah . The Quraysh united their forces and the bedouins who joined them for the battle of Uhud, during which Allah tested the Muslims, but the good end is always for the pious and righteous people. The rebellious Abu `Amir dug many holes in the ground between the two camps, into one of which the Messenger fell, injuring his face and breaking one of his right lower teeth. He also sustained a head injury. Before the fighting started, Abu `Amir approached his people among the Ansar and tried to convince them to support and agree with him. When they recognized him, they said, â€May Allah never burden an eye by seeing you, O Fasiq one, O enemy of Allah!'' They cursed him and he went back declaring, â€By Allah! Evil has touched my people after I left.'' The Messenger of Allah called Abu `Amir to Allah and recited the Qur'an to him before his flight to Makkah, but he refused to embrace Islam and rebelled. The Messenger invoked Allah that Abu `Amir die as an outcast in an alien land, and his invocation came true. After the battle of Uhud was finished, Abu `Amir realized that the Messenger's call was still rising and gaining momentum, so he went to Heraclius, the emperor of Rome, asking for his aid against the Prophet . Heraclius gave him promises and Abu `Amir remained with him. He also wrote to several of his people in Al-Madinah, who embraced hypocrisy, promising and insinuating to them that he will lead an army to fight the Messenger of Allah to defeat him and his call. He ordered them to establish a stronghold where he could send his emissaries and to serve as an outpost when he joins them later on. These hypocrites built a Masjid next to the Masjid in Quba', and they finished building it before the Messenger went to Tabuk. They went to the Messenger inviting him to pray in their Masjid so that it would be a proof that the Messenger approved of their Masjid. They told him that they built the Masjid for the weak and ill persons on rainy nights. However, Allah prevented His Messenger from praying in that Masjid. He said to them,
