QSI: The Seerah Of Prophet Muhammad (pbuh) #43

In March 624, Muslims led by Muhammad defeated the Meccans of the Banu Quraish tribe in the Battle of Badr. Ibn Ishaq writes that a dispute broke out between the Muslims and the Banu Qaynuqa (the allies of the Khazraj tribe) soon afterwards. When a Muslim woman visited a jeweler's shop in the Qaynuqa marketplace, she was molested. The goldsmith, a Jew, pinned her clothing such that, upon getting up, she was stripped naked. A Muslim man coming upon the resulting commotion killed the shopkeeper in retaliation. A mob of Jews from the Qaynuqa tribe then pounced on the Muslim man and killed him. This escalated to a chain of revenge killings, and enmity grew between Muslims and the Banu Qaynuqa
