The most powerful and prominent tribe in all of Arabia in the Prophet's era. The Quraysh were the keepers of the Ka'bah and therefore one of the wealthiest and most powerful tribes. The Prophet was from among the Quraysh. When he started to preach the True religion of Allah, the Quraysh violently persecuted him and his followers. They were badly defeated at the battle of Badr by the Muslims and their days of jahiliyyah were finally ended when the Muslims liberated Mecca and destroyed all the idols in the Ka'bah in the year 630 CE
