Struggle Against Intolerance and Unbelief
Not content with the expulsion of the Muslim compatriots, the Meccans sent an ultimatum to the Madinans, demanding the surrender or at least the expulsion of Muhammad and his companions but evidently all such efforts proved in vain. A few months later, in the year 2 A. H., they sent a powerful army against the Prophet, who opposed them at Badr; and the pagans thrice as numerous as the Muslims, were routed. After a year of preparation, the Meccans again invaded Madinah to avenge the defeat of Badr. They were now four times as numerous as the Muslims. After a bloody encounter at Uhud, the enemy retired, the issue being indecisive. The mercenaries in the Meccan army did not want to take too much risk, or endanger their safety.
In the meanwhile the Jewish citizens of Madinah began to foment trouble. About the time of the victory of Badr, one of their leaders, Ka’b ibn al-Ashraf, proceeded to Mecca to give assurance of his alliance with the pagans, and to incite them to a war of revenge. After the battle of Uhud, the tribe of the same chieftain plotted to assassinate the Prophet by throwing on him a mill-stone from above a tower, when he had gone to visit their locality. In spite of all this, the only demand the Prophet made of the men of this tribe was to quit the Madinan region, taking with them all their properties, after selling their immovable items and recovering their debts from the Muslims. The clemency thus extended had an effect contrary to what was hoped. The exiled not only contacted the Meccans, but also the tribes of the North, South and East of Madinah, mobilized military aid, and planned from Khaibar an invasion of Madinah, with forces four times more numerous than those employed at Uhud. The Muslims prepared for a siege, and dug a ditch to defend themselves against this hardest of all trials. Although the defection of the Jews still remaining inside Madinah at a later stage upset all strategy, yet with a sagacious diplomacy, the Prophet succeeded in breaking up the alliance, and the different enemy groups retired one after the other.
Alcoholic drinks, gambling and games of chance were at this time declared forbidden for the Muslims.
