It was narrated from Sulaiman bin 'Amr bin Ahwas that his father said: "I heard the Prophet ﷺ say, during the Farewell Pilgrimage: 'O people! Which day is the most sacred?’ three times. They said: 'The day of the greatest Hajj.’ He said: 'Your blood and your wealth and your honor are sacred to one another, as sacred as this day of yours, in this land of your. No sinner commits a sin but it is against himself. No father is to be punished for the sins of his child, and no child is to be punished for the sins of his father. Satan has despaired of ever being worshipping in this land of yours, but he will be obeyed in some matters which you regard as insignificant, and he will be content with that. All the blood feuds of the Ignorance days are abolished, and the first of them that I abolish is the blood feud of Harith bin 'Abdul-Muttalib, who was nursed among Banu Laith and killed by Hudhail. All the usuries of the Ignorance days are abolished, but you will have your capital. Do not wrong others and you will not be wronged. O my nation, have I conveyed (the message)?’ (He asked this) three times. They said: 'Yes.’ He said: 'O Allah, bear witness!’ three times".
This hadith teaches us many important values such as justice and fairness towards others regardless of their background or beliefs; protection for our own blood, wealth and honor; respect for ourselves; understanding that no one should be punished for another person’s sins; forgiveness towards those who have wronged us in any way; abstaining from taking advantage of others financially through unfair means such as usury; understanding that even though Satan cannot lead people astray in this land anymore we must still remain vigilant against his influence on our thoughts and actions; lastly it teaches us to always strive to do good deeds so we can benefit ourselves spiritually in both worlds.
