# The Expedition of Tabuk

The Most Difficult March

The Expedition of Tabuk — known as al-Ghazwa al-Usra (the Expedition of Hardship) — was the last major military campaign of the Prophet's ﷺ life, undertaken in Rajab 9 AH in conditions of extraordinary difficulty. The Prophet ﷺ received intelligence that the Byzantine Empire, still in the aftermath of Heraclius's Persian wars and now facing a Muslim Arabia it had not fully confronted, was assembling a large force at the Syrian frontier to march against the Muslim community. He called for a general mobilization, and in an unprecedented act, he asked the wealthy companions to donate openly and publicly — naming Abu Bakr, Umar, and Uthman specifically.

The circumstances were as difficult as any the community had faced. It was the height of summer — one of the hottest on record in Arabia. The harvest season was approaching; the date crop was ripe and the farmers were reluctant to leave. The journey to Tabuk from Medina was approximately 700 kilometers — a march through desert in peak heat. Food and water would be scarce. The hypocrites found many excuses not to go.

The Companions' Response

The response of the sincere companions was a demonstration of the community's character. Abu Bakr brought everything he owned — his entire household wealth — and when the Prophet ﷺ asked what he had left for his family, he said: "Allah and His Messenger." Umar brought half of his wealth. Uthman ibn Affan — who had given generously before — equipped an entire third of the army from his own wealth: 300 camels fully equipped, 10,000 dinars, additional horses. The Prophet ﷺ said: "Nothing Uthman does after today can harm him." The hadith is understood as a declaration of Uthman's paradise from that moment forward.

Even a poor companion named Abu Aqil brought a sa' (a small measure) of dates — all he had earned by carrying water at night — and the hypocrites mocked his contribution. The Quran addressed both: the generous gave abundantly and the mockers found fault (Surah al-Tawbah 9:79). Women gave jewelry. Those who could not go wept. The army that departed for Tabuk numbered approximately 30,000 — the largest the Prophet ﷺ had ever commanded.

The March and the Arrival

The conditions on the march were severe. The hadith literature preserves accounts of the water running out, of camels being slaughtered for the water in their stomachs, of the Prophet ﷺ making du'a over small amounts of water that were then sufficient for thousands. The army arrived at Tabuk and found no Byzantine force waiting — the anticipated invasion had either been a false report or had been called off by Heraclius, who had by this point abandoned his initial impulse to engage the Muslims directly. The Prophet ﷺ remained at Tabuk for approximately twenty days, securing treaties with the border tribes and Christian communities of the region, then returned to Medina.

The Three Who Stayed Behind

Among the consequences of the expedition was the case of Ka'b ibn Malik, Murarah ibn al-Rabi, and Hilal ibn Umayyah — three sincere Muslims who had no excuse and stayed behind without one. They were not hypocrites; they did not deny they had stayed without reason. When the Prophet ﷺ returned, he refused to speak to them and instructed the community not to speak to them either. For fifty days they were socially isolated — their own families not speaking to them, every person in Medina turning away from their greetings. Ka'b ibn Malik's account of those fifty days is one of the most remarkable personal narratives in the hadith literature: the earth, for all its vastness, narrowing around him, his own soul narrowing within him, until the revelation came and he was forgiven. Surah al-Tawbah (9:118) records the forgiveness: "And upon the three who were left behind — until the earth was confining for them despite its vastness, and their very souls were confining to them, and they were certain that there was no refuge from Allah except in Him. Then He turned to them so they could repent."

The Munafiqun and Surah al-Tawbah

The Expedition of Tabuk produced the most extensive Quranic commentary on the hypocrites that exists in the revelation. Surah al-Tawbah — the ninth surah and one of the last to be revealed — was largely concerned with the events of Tabuk: the behavior of those who made excuses, those who swore false oaths, those who built the rival mosque (Masjid al-Dirar) as a center for opposition. The surah names the hypocrites' arguments one by one and addresses them. It is the only surah that does not begin with Bismillah — a fact the classical scholars associated with its tone: al-Tawbah carries no opening mercy formula because it was revealed as a final warning, without conciliation.

The surah also addresses those who gave genuine excuses — the poor who had no mount and were turned away weeping, the blind, the sick — and distinguishes them sharply from those who stayed behind to pursue wealth or pleasure. The moral geography of Tabuk that the Quran draws is precise: it sorts the community into those who responded at cost to themselves, those who were genuinely unable, those who stayed without legitimate reason (Ka'b and his companions, who were forgiven), and those who were never going to go regardless of circumstances (the hypocrites). Each category receives its own Quranic verdict.

The Strategic Legacy

The Expedition of Tabuk settled the question of the Muslim community's western frontier without a battle. The treaties secured with the border tribes and the Christian communities of Ayla, Jarba, and Adhruh established the Muslim community's presence at the edge of Byzantine territory and demonstrated that the Prophet ﷺ could project force to the Syrian frontier — a distance from Medina that most armies of that era would have considered beyond practical reach. The Byzantines did not follow through on any attack, and the Muslim community returned with its standing in northern Arabia permanently elevated. The failure of the Byzantine threat to materialize was itself a strategic outcome: it demonstrated that the Muslim state could mobilize and march even in extreme conditions, and that the hypocrites' predictions of defeat and disaster were unfounded.
