What did the Prophet (saw) invoke on the people of Quraish?
 Narrated `Abdullah bin Mas`ud:                     The Prophet faced the Ka`ba and invoked evil on some people of Quraish, on Shaiba bin Rabi`a, `Utba bin Rabi`a, Al-Walid bin `Utba and Abu Jahl bin Hisham. I bear witness, by Allah, that I saw them all dead, putrefied by the sun as that day was a very hot day.
