When the Holy Prophet (s) concluded the rituals of Hajj, he stood besides the Zamzam well and ordered Rabi bin Umayyah bin Khalaf, a young man to stand below the chest of his horse. Then he said, “O Rabi! Say: O people! The Messenger of Allah (s) is telling you: Maybe you would never see me in this condition and yourself in this condition. Do you know what it is?

And the first murder that we put below our feet is that of Adam bin Rabia bin Harith bin Abdul Muttalib.
[1] Have I made myself clear?” “Yes”, they replied. His Eminence said, “O Allah be witness! And we have destroyed all usury that was in the period of ignorance. And the first usury that I have destroyed is that of Abbas bin Abdul Muttalib. Have I made myself clear?” “Yes”, they replied. His Eminence said, “O Allah, be witness! O people!
