At first, when Mahomet commanded that these caravans should be attacked and looted, his followers looked aghast, for the sacredness of tribes from attack by kinsmen was a tradition they had inherited for generations. Their Prophet at once proved to them by a message from Allah that a new relationship had been formed stronger than the ties of blood, namely, the bond of faith, and that to the believer the unbeliever, whether father or son, was accursed. In the same way, when the first marauding expeditions were unsuccessful because the caravans attacked were too well guarded, Mahomet explained away the ‘Sacred Months’ and chose in future that very time for his warriors to descend upon unsuspecting merchants.
The Meccans, outraged by what they somewhat naturally considered treachery, soon dispatched some thousand men, determined to make an end of the Prophet and his followers; and at Badr, not very far from the coast on the trade route between the two towns, this large force encountered three hundred Moslems commanded by Mahomet. It is difficult to gain a clear impression of the battle, for romance and legend have rendered real details obscure; but, either by superior generalship, the valour and discipline of the Moslems as compared to the conduct of their forces, or, as was later stated, through the agency of angels sent by Allah from Heaven, the vastly more numerous Meccan force was utterly put to rout.
Moslems refer to the battle of Badr as ‘the Day of Deliverance’, for though, not long afterwards, they in their turn were defeated by the Meccans, yet never again were they to become mere discredited refugees. Success pays, and, with the victory of Badr as a tangible miracle to satisfy would-be converts, Mahomet soon gained a large army of warriors, whom his personality moulded into obedience to his will.
The Jews who had mocked him had soon cause to repent, for Mahomet, remembering their jibes and the petty persecution to which they had subjected his followers, adopted a definitely hostile attitude towards them. Taking advantage of the reluctance with which these Jews had shared in the defence of Medinah and in the throwing-up of earthworks to protect it, when the Meccans came to besiege it in the year 5 of the new calendar, Mahomet as soon as the siege was raised obtained his revenge. Those Jews of the city who still refused to recognize him as a Prophet were slaughtered, their wives and children sold into slavery. The teaching and ritual of the Koran also, once carefully based on the Scriptures of Israel, began to cast off this influence, and where of old Mahomet had commanded his followers to look towards Jerusalem in their prayers, he now bade them kneel with their faces towards Mecca.
