Sahih al-Bukhari 4445
صحيح البخاري#4445SahihAisha added, "I argued with Allah's Messenger (ﷺ) repeatedly about that matter (i.e. his order that Abu Bakr should lead the people in prayer in his place when he was ill), and what made me argue so much, was, that it never occurred to my mind that after the Prophet, the people would ever love a man who had taken his place, and I felt that anybody standing in his place, would be a bad omen to the people, so I wanted Allah's Messenger (ﷺ) to give up the idea of choosing Abu Bakr (to lead the people in prayer)
