It wasnarrated from Sulaiman bin 'Amr bin Ahwas that his fathersaid:
"Iheard the Prophet (ﷺ) say, during the Farewell Pilgrimage:'Opeople! Which day is the most sacred?' three times. They said: 'Theday of the greatest Hajj.' He said: 'Your blood and your wealthandyour honor are sacred to one another, as sacred as this day ofyours,in this land of your. No sinner commits a sin but it isagainsthimself. No father is to be punished for the sins of hischild, and nochild is to be punished for the sins of his father.Satan hasdespaired of ever being worshipping in this land of yours,but he willbe obeyed in some matters which you regard asinsignificant, and hewill be content with that. All the blood feudsof the Ignorance daysare abolished, and the first of them that Iabolish is the blood feudof Harith bin 'Abdul-Muttalib, who wasnursed among Banu Laith andkilled by Hudhail. All the usuries of theIgnorance days areabolished, but you will have your capital. Do notwrong others and youwill not be wronged. O my nation, have Iconveyed (the message)?' (Heasked this) three times. They said:'Yes.' He said: 'O Allah, bearwitness!' three times."
