“A perfect man rose from the children of Ibraheem (AS) whose name was Muhammad ibn Abdullah (SAW). He (SAW) revived the genuine and pure religion of Islamic Monotheism. He (SAW) purified the Ka'baah of idols and revived Tawheed in its purity. Prophet Muhammad (SAW) exterminated all the shameful and brutal practices of Jahiliyya (ignorance) which Arabs were accustomed to -- idol worship, spattering the blood and flesh of sacrificed animals on the walls of the Ka'baah, obscene behavior, indecency, wrangling, circumambulation of the Ka'baah in the state of nudity and other evil customs. Thus the Ka'baah regained its real position as the focus of Tawheed and Hajj was re-established in its real meaning and content.” Hajj started with Ibrahim who left his legacy both in the Hanifiyah, the pristine religion of Islam, and in Hajj. The legacy of Ibrahim was his way of true submission to Allah. He was the first one who used the word “Islam”. Islam means to surrender and submit to the will of the Creator.
