It was narrated from `Uthman bin `Affan (رضي الله عنه). `Abdullah bin az-Zubair said to him when he was besieged:
I have camels that I have prepared for you; do you want to go to Makkah, then whoever wants to see you can come and see you? He said: No, I heard the Messenger of Allah (ﷺ) say: `A ram of Quraish whose name is ‘Abdullah will seek to commit profanity and wrongdoing in Makkah; he will have half of the burden of mankind`s sins.”
