Jist of The Farewell (Hajj) Sermon
people! Allah says, O men, who were created from a man and woman, divided into castes and tribes to identify each other; you are equal, but he is more respectable who fears Allah. All Muslims are brothers together. Be careful of the rights of your slaves. Men and women have their duties and rights to eachother. Offer prayers to Allah five times a day, fast the full month of Ramadan, pay zakat every year, perform Hajj and obey your rulers. Thus enter the Heavan created by Allah
