Nu'aym ibn Mas'ud's Secret Conversion and the Triple Deception
historicalShaykh Yasir Qadhi explains:
As the siege approached its final days, roughly around the twentieth day by rough estimate, the turning point of the entire Battle of the Trench arrived through a man the classical Sīrah sources mention only in passing, since he belonged to neither Makkah nor Madinah: Nuʿaym ibn Masʿūd of the tribe of Ghaṭafān.
Dr. Qadhi reconstructs Nuʿaym's background, noting explicitly that this reconstruction is his own theory rather than established history. In 4 AH, still a polytheist and a business associate of Abū Sufyān, Nuʿaym had been paid to travel to Madinah and falsely warn the Prophet ﷺ of an overwhelming Qurashī force at the agreed second meeting at Badr, a lie meant to discourage the Muslims from showing up, so blame for abandoning the agreement would fall on them. The Prophet ﷺ declared he would go even alone, and the Muslims marched to Badr while Quraysh never appeared. Around the same period, Nuʿaym also negotiated a minor treaty with the Prophet ﷺ on behalf of his own sub-tribe. Dr. Qadhi's theory is that these two direct encounters, during which Ghaṭafān remained officially neutral and Nuʿaym alone among his tribe interacted personally with the Prophet ﷺ, left a deep impression that led to his secret conversion sometime before the Trench.
Nuʿaym slipped away from the Ghaṭafān camp one night and declared his Islam directly to the Prophet ﷺ, asking to be given any task. Told that a single fighter would add little to the Muslims' military position, he was instructed instead to weaken the Confederates from within by whatever means he could devise. Asking explicit permission to use tactics short of honesty, he received the Prophet's ﷺ famous reply: "al-ḥarbu khidʿah" (الْحَرْبُ خُدْعَةٌ), war is deception. Dr. Qadhi draws a sharp distinction here between khidʿah (deception through misdirection or tactical illusion, permitted in genuine warfare and practiced by every nation throughout history) and khiyānah (treachery, breaking an actual promise, treaty, or oath, which Islam never permits under any circumstance, including obligations implicit in something like a visa or passport).
Drawing on personal trust built over years with all three Confederate parties, Nuʿaym set his plan in motion. He first went to Banū Qurayẓah, warning them that Quraysh, unlike themselves, had nothing to lose by abandoning the siege and going home, while Qurayẓah stood to lose everything; his advice was to refuse further fighting until Quraysh handed over hostages from among their own nobility as a guarantee they would not simply retreat. He then went separately to Abū Sufyān, warning him, under the guise of old loyalty, that Banū Qurayẓah had grown fearful and had secretly offered the Prophet ﷺ some of Quraysh's own nobles in exchange for forgiveness of their earlier hesitation, and that any Qurayẓī request for Qurashī hostages should be read as confirmation of this betrayal. He gave a parallel warning to his own tribe of Ghaṭafān. Within hours, an emissary from Banū Qurayẓah did arrive asking Quraysh to send hostages, exactly as Nuʿaym had primed Abū Sufyān to expect, and Abū Sufyān, now suspicious, stalled rather than comply. The same pattern played out with Ghaṭafān. Each of the three parties, now doubting the others' loyalty, refused to move first, the beginning of the coalition's unraveling, with the rest of the story continuing from there.
❧THE FULLER ACCOUNT, IN NUʿAYM'S OWN WORDS
Imam al-Wāqidī's Kitāb al-Maghāzī preserves a rare first-person narration from Nuʿaym himself, one of the very few Companions whose account of his own conversion survives in this form. He describes his pre-Islamic relationship with Banū Qurayẓah candidly: he would travel to them to drink wine, share meals, and purchase dates before returning to Ghaṭafān. Then, camped with the Confederate army outside Madinah, he says simply, "Allah threw Islam into my heart" (أَلْقَى اللَّهُ الْإِسْلَامَ فِي قَلْبِي, alqā Allāh al-Islāma fī qalbī), with no further explanation of how or why. He went that night to the Prophet ﷺ and found him praying; when the Prophet ﷺ finished, he greeted Nuʿaym by name, "O Nuʿaym, what has brought you?", confirming the Prophet ﷺ already recognized him from their prior, religiously neutral dealings.
❧THE ESCALATION TO SEVENTY HOSTAGES
Nuʿaym's plan escalated in its final stage: he told Banū Qurayẓah that their security depended on securing seventy of Quraysh and Ghaṭafān's own noblemen (ashrāf) as hostages, specifically nobles, since ordinary men or slaves could simply flee, whereas tribes would not abandon their own leaders. He then separately warned Abū Sufyān, under the guise of old loyalty, that Banū Qurayẓah intended to hand over exactly seventy Qurashī hostages to the Prophet ﷺ as expiation for their earlier hesitation, meaning any Qurayẓī request for seventy hostages should be read as a trap. When Banū Qurayẓah's emissary, ʿAzzāl ibn Samaw'al, arrived to press Quraysh for the hostages and to propose a coordinated attack date, Abū Sufyān stalled. Nuʿaym then returned to Banū Qurayẓah the next day and fabricated an inflammatory report, that Abū Sufyān had sworn he would not hand over even a single young camel, let alone seventy nobles, since he suspected Qurayẓah intended to kill them and hand them to the Prophet ﷺ regardless. This confirmed Banū Qurayẓah's worst fears of betrayal, and it was at this point that Kaʿb ibn Asad, sensing the plan collapsing, began openly cursing Huyayy ibn Akhṭab for having drawn him into the alliance in the first place. Al-Zubayr ibn Bāṭā, another figure of the tribe, argued with cold clarity that the demand had never made sense to begin with: Quraysh and Ghaṭafān had the numbers and the option to retreat, while Qurayẓah, trapped inside the city, faced nothing but the sword if the Confederates abandoned them, a recognition, Dr. Qadhi notes, that shows the tribe already understood the gravity of the punishment its betrayal had invited.
❧THE ULTIMATUM AND THE SABBATH
Frustrated by the stalemate and fearing Qurayẓah's flip against them, Abū Sufyān resolved on a surprise coordinated assault the very next morning, sending a senior delegation led by ʿIkrimah ibn Abī Jahl to demand Qurayẓah's immediate participation. The delegation arrived on a Friday afternoon; the next day was Saturday, and Banū Qurayẓah refused to fight on the Sabbath, asking instead for a delay until Sunday, while still insisting on their seventy hostages regardless. Quraysh, unfamiliar with Jewish law and suspecting only another stalling tactic, grew furious. Abū Sufyān summoned Huyayy, present in the Qurashī camp at the time, to explain the custom, but dismissed his explanation as an invented excuse, accusing him outright of deceit. Fearing for his safety, Huyayy fled back to Banū Qurayẓah and pressed them to break the Sabbath, provoking Kaʿb ibn Asad's fury at being told to violate his own religious law by a man who claimed to be his ally. Kaʿb refused, declaring he would rather be killed than break the Sabbath. Too afraid to return to the Qurashī camp after this exchange, Huyayy chose to remain inside Banū Qurayẓah's fortress, a decision that trapped him there when the Confederates withdrew that same night, sealing his own fate alongside the tribe he had persuaded to betray its treaty.
