Sulayman bin Amr bin al-Ahwas narrates from his father (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say during the Farewell Pilgrimage: "Which day is the greatest in sanctity?" The people said: Today, the day of the Greater Hajj. He said: "Your wealth, your honour and your blood are sacred, just as this city and this day are sacred. No one shall commit an offence against another: no child will suffer for what his father did, and no father will bear the burden of his child."
