The First Expeditions
The Prophet’s first concern as ruler was to establish public worship and lay down the constitution of the State: but he did not forget that Quraysh had sworn to make an end of his religion, nor that he had received command to fight against them till they ceased from persecution. After he had been twelve months in Yathrib several small expeditions went out, led either by the Prophet himself or some other of the fugitives from Makkah for the purpose of reconnoitering and of dissuading other tribes from siding with Quraysh. These are generally represented as warlike but, considering their weakness and the fact that they did not result in fighting; they can hardly have been that, though it is certain that they went out ready to resist attack. It is noteworthy that in those expeditions only fugitives from Makkah were employed, never natives of Yathrib; the reason being (if we accept Ibn Khaldun’s theory, and there is no other explanation) that the command to wage war had been revealed to the Prophet at Makkah after the Yathrib men had sworn their oath of allegiance at al-‘Aqabah, and in their absence. Their oath foresaw fighting in mere defense not fighting in the field. Blood was shed and booty taken in only one of those early expeditions, and then it was against the Prophet’s orders.
One purpose of those expeditions may have been to accustom the Makkah Muslims to going out in war like trim. For thirteen years they had been strict pacifists, and it is clear, from several passages of the Qur’an, that many of them, including, it may be, the Prophet himself, hated the idea of fighting even in self-defense and had to be inured to it.

The Campaign of Badr
In the second year of the Hijrah the Makkahn merchants’ caravan was returning from Syria as usual by a road which passed not far from Yathrib. As its leader Abu Sufyan approached the territory of Yathrib he heard of the Prophet’s design to capture the caravan. At once he sent a camel-rider on to Makkah, who arrived in a worn-out state and shouted frantically from the valley to Quraysh to hasten to the rescue unless they wished to lose both wealth and honor. A force a thousand strong was soon on its way to Yathrib: less, it would seem, with the hope of saving the caravan than with the idea of punishing the raiders, since the Prophet might have taken the caravan before the relief force started from Makkah.
Did the Prophet ever intend to raid the caravan? In Ibn Hisham, in the account of the Tabuk expedition, it is stated that the Prophet on that one occasion did not hide his real objective. The caravan was the pretext in the campaign of Badr; the real objective was the Makkan army.
He had received command to fight his persecutors, and promise of victory, he was prepared to venture against any odds, as was well seen at Badr. But the Muslims, ill-equipped for war, would have despaired if they had known from the first that they were to face a well-armed force three times their number.
The victory of Badr gave the Prophet new prestige among the Arab tribes |
The army of Quraysh had advanced more than half-way to Yathrib before the Prophet set out. All three parties – the army of Quraysh, the Muslim army and the caravan – were heading for the water of Badr. Abu Sufyan, the leader of the caravan, heard from one of his scouts that the Muslims were near the water, and turned back to the coast-plain. And the Muslims met the army of Quraysh by the water of Badr.
Before the battle the Prophet was prepared still further to increase the odds against him. He gave leave to all the Ansar (natives of Yathrib) to return to their homes unreproached, since their oath did not include the duty of fighting in the field; but the Ansar were only hurt by the suggestion that they could possibly desert him at a time of danger. The battle went at first against the Muslims, but ended in a signal victory for them.
The victory of Badr gave the Prophet new prestige among the Arab tribes; but thenceforth there was the feud of blood between Quraysh and the Islamic State in addition to the old religious hatred. Those passages of the Qur’an which refer to the battle of Badr give warning of much greater struggles yet to come.
In fact in the following year, an army of three thousand came from Makkah to destroy Yathrib. The Prophet’s first idea was merely to defend the city, a plan of which Abdullah ibn Ubeyy, the leader of “the Hypocrites” (or lukewarm Muslims), strongly approved. But the men who had fought at Badr and believed that God would help them against any odds thought it a shame that they should linger behind
