In 632, at the end of the tenth year after migration to Medina, Muhammad completed his first true Islamic pilgrimage, setting precedent for the annual Great Pilgrimage, known as Hajj. On the 9th of Dhu al-Hijjah Muhammad delivered his Farewell Sermon, at Mount Arafat east of Mecca. In this sermon, Muhammad advised his followers not to follow certain pre-Islamic customs. For instance, he said a white has no superiority over a black, nor a black any superiority over a white except by piety and good action. He abolished old blood feuds and disputes based on the former tribal system and asked for old pledges to be returned as implications of the creation of the new Islamic community. Commenting on the vulnerability of women in his society, Muhammad asked his male followers to be good to women, for they are powerless captives (awan) in your households. You took them in God's trust, and legitimated your sexual relations with the Word of God, so come to your senses people, and hear my words ... He told them that they were entitled to discipline their wives but should do so with kindness. He addressed the issue of inheritance by forbidding false claims of paternity or of a client relationship to the deceased and forbade his followers to leave their wealth to a testamentary heir. He also upheld the sacredness of four lunar months in each year. According to Sunni tafsir, the following Quranic verse was delivered during this event: Today I have perfected your religion, and completed my favours for you and chosen Islam as a religion for you (Quran 5:3). According to Shia tafsir, it refers to the appointment of Ali ibn Abi Talib at the pond of Khumm as Muhammad's successor, this occurring a few days later when Muslims were returning from Mecca to Medina.
