Conquest of Mecca
Upon the Conquest of Mecca in January 630, Muhammad found that the Kaaba was locked. He said, "'Who has the key?'" and was told that Uthman Ibn Talha had it. Muhammad told Ali to take the key from Uthman. Ali went to him and asked, "Can you please give me key?". Uthman replied, "Why you are asking? Is someone at Mecca?". Ali replied, "Muhammad wants this key to enter the Kaaba." Uthman refused to hand it over. Ali snatched key from him and gave it to Muhammad.
