The Youth Quarrel and Abdullah ibn Ubayy's Statement

Shaykh Yasir Qadhi explains:

Al-Muraysīʿ saw the largest concentration of hypocrites of any expedition in the Sīrah, the campaign was nearby, promised a guaranteed and effectively bloodless victory, and fell outside harvest season, removing every excuse hypocrites had used to stay behind from Badr, Uḥud, and every campaign since. With that concentration came friction.

❧THE QUARREL

Two young men, one Anṣārī, one Muhājir, sent to draw water for the caravan, fell into a petty dispute (the sources deliberately do not record what it was about) that escalated to blows. Each called out to his own group for support, "O Muhājirūn!" "O Anṣār!", and within moments the entire camp had split along Muhājir/Anṣār lines, shouting, lining up, and nearly drawing weapons over a fight neither side could even properly explain.

The Prophet (ﷺ) rushed out and rebuked both sides sharply: "A bi-daʿwā al-jāhiliyyah, are you invoking the rallying cries of the Age of Ignorance?", and declared the whole impulse "muntinah," rotting, filthy, something to be discarded outright. He did not investigate who struck first or what the original dispute even was, resolving the matter with a single command to drop it entirely, a deliberate choice, since digging into the particulars would only have inflamed tempers further.

Dr. Qadhi draws out the deeper lesson here: even a division with genuine Qur'ānic standing, Muhājir and Anṣār, could be twisted into something un-Islamic and divisive when wielded the wrong way, which raises the question of how much more dangerous purely man-made divisions (tribal, ethnic, regional) are when allowed to operate the same way within the Ummah.

❧ʿABDULLĀH IBN UBAYY'S STATEMENT

ʿAbdullāh ibn Ubayy ibn Salūl, who had mocked the Prophet (ﷺ) openly before his reluctant post-Badr conversion, and had already shown his true loyalties at Uḥud, was privately furious that the dispute had been defused rather than escalated. Among his own circle, he complained that the Muhājirūn had grown to rival the Anṣār in number, comparing the situation to the Arabic proverb about fattening a dog only for it to turn and bite you, and declared: "Wallāhi, la-in rajaʿnā ilā al-Madīnati la-yukhrijanna al-aʿazzu minhā al-adhall", by Allah, when we return to Madinah, the more honored [meaning himself and the Anṣār elite] will expel the more disgraced [meaning the Muhājirūn] from it. He went further, blaming his own followers for the Muhājirūn's presence in the first place, for having shared their wealth and land so freely.

A young Companion present, Zayd ibn Arqam, could not let this pass, it amounted to open kufr and mockery of the Prophet (ﷺ) himself. He rushed to his uncle, who took him directly to the Prophet (ﷺ) to report exactly what he had heard. Called to answer for it, ʿAbdullāh ibn Ubayy swore the strongest oaths he could muster, denying it entirely and dismissing Zayd as an unreliable young witness. Given the gravity of the accusation weighed against a mere child's word, the Prophet (ﷺ) accepted his denial rather than condemn him, a decision that visibly strained relations between the Anṣār (already furious with Ibn Ubayy) and the hypocrites who rallied to defend him.

ʿUmar ibn al-Khaṭṭāb asked permission on the spot to execute him outright: "Daʿnī aḍribu ʿunuqahu, let me strike his neck." The Prophet (ﷺ) refused: "Daʿhu, leave him. I do not want it said that Muḥammad kills his own companions." He then ordered the entire army to break camp immediately and march non-stop, a continuous twenty-hour march through the rest of the day and the following night, reaching the outskirts of Madinah utterly exhausted, with no time or energy left to gossip or let the incident fester before collapsing into sleep on arrival.

❧THE REVELATION

Zayd ibn Arqam, meanwhile, was devastated, his sincere report had effectively been disbelieved. That very morning outside Madinah, Allah revealed the entirety of Sūrah al-Munāfiqūn, vindicating him explicitly: "Idhā jāʾaka al-munāfiqūna qālū nashhadu innaka la-Rasūlullāh... wallāhu yashhadu inna al-munāfiqīna la-kādhibūn", when the hypocrites come to you they claim to bear witness that you are the Messenger of Allah, and Allah bears witness that the hypocrites are truly liars. The surah quotes ʿAbdullāh ibn Ubayy's statement verbatim, "layukhrijanna al-aʿazzu minhā al-adhall", preserved in the Qurʾān to this day, before affirming that all honor belongs to Allah, His Messenger, and the believers.

On hearing the revelation, the Prophet (ﷺ) took hold of Zayd ibn Arqam's ear and told him Allah Himself had confirmed his ears had heard the truth, a personal reassurance to a young man who had just spent one of the most painful nights of his life for having told the truth and not been believed.
