Masjid al-Ḍirār: The Mosque of Harm

Shaykh Yasir Qadhi explains:

The final incident is the mosque the hypocrites built. Refusing a coin for Tabūk, they yet found the funds to raise their own masjid, a place to gather and preach freely, close to Masjid Qubāʾ, with Ibn Ubayy to lead it. But there was a deeper plot behind it.

❧Abū ʿĀmir's plot from Rome

Its true instigator was Abū ʿĀmir al-Rāhib ("the monk"), the former Aws leader who had rejected Islam, been publicly disowned by his own tribe at Uḥud ("You are not al-Rāhib but al-Fāsiq!"), fled to Makkah, and finally to Byzantine Rome, where he reached the ear of Caesar. From there he wrote to his friend Ibn Ubayy: prepare me a base in Medina, and I will bring Roman troops to overthrow the Muslims. The mosque was to be that base, which is why the Prophet ﷺ made duʿāʾ that Abū ʿĀmir die a lonely stranger, and so he did, far from kin in Rome.

❧The Prophet's ﷺ evasion, and the verses

Ibn Ubayy invited the Prophet ﷺ to pray two rakʿāt to inaugurate it, pleading it was for the weak and the elderly on rainy nights. Sensing wrong yet not wishing to refuse outright, he ﷺ said only, "We are busy preparing to travel; when I return, if Allāh wills." He never prayed there. On the way back from Tabūk, Jibrīl brought down the verdict (9:107–108): وَالَّذِينَ اتَّخَذُوا مَسْجِدًا ضِرَارًا وَكُفْرًا وَتَفْرِيقًا بَيْنَ الْمُؤْمِنِينَ وَإِرْصَادًا لِّمَنْ حَارَبَ اللَّهَ وَرَسُولَهُ, a mosque of harm, of disbelief, of division among the believers, and an ambush-post for one who had made war on Allāh and His Messenger, "and they will surely swear they intended only good; Allāh bears witness they are liars." لَا تَقُمْ فِيهِ أَبَدًا, "never stand in it"; rather the mosque founded on taqwā from the first day is worthier. So the Prophet ﷺ sent ʿAmmār ibn Yāsir and others to burn it to the ground. This ended the hypocrites' aspirations, the final open stand between them and the Prophet ﷺ before the death of Ibn Ubayy.

❧The mosque of taqwā and a caution

The "mosque founded on taqwā" (9:108) is variously said to be Qubāʾ (whose people Allāh praised for loving to purify themselves, fīhi rijālun yuḥibbūna an yataṭahharū, linked to their habit of washing with water, the fiqh of istinjāʾ) or the Prophet's ﷺ own Mosque (which he affirmed by oath in Musnad Aḥmad); the soundest view is that the verse is general, embracing both. Yet a Masjid al-Ḍirār is a grave charge: it broke away not from a community of men but from the Prophet ﷺ himself. To brand a rival mosque "Ḍirār" merely because a community split over a disagreement, as too often happens, is arrogant and dangerous, for it accuses fellow Muslims of intending kufr. Leave that verdict to Allāh: live and let live; a sincere mosque will flourish, and an insincere one Allāh will expose.
