In How old was Aisha when she married the Prophet (s)?, Dr. Jasser Auda◊ writes about ahadith describing Aisha's age of consummation:
... Unexpectedly Allah's Apostle came to me in the forenoon and my mother handed me over to him, and at that time I was a girl of nine years of age. -- Sahih al-Bukhari 3894 (sunnah.com)
along with Sahih Muslim 1422 a-d (sunnah.com). He says other Bukhari ahadith logically contradict the "nine years old" narration, giving several ahadith as particular examples. One of these is described as follows:
Bukhari himself also narrates (No. 2176) that Aisha witnessed her father’s attempt to migrate to Abyssinia, which was during the Year 4 of the Message (Year 9 Before Hijra) according to all accounts. This witnessing could not have happened before Aisha herself was born, as the "nine years old" hadith implies!
I surmise this refers to Sahih al-Bukhari 3905 (sunnah.com) where Aisha narrates her father's attempted migration to "the land of Ethiopia" (Abyssinia) in considerable detail.
So the logic is:
Aisha witnessed her father’s attempt to migrate to Abyssinia in the year 9 BH. Thus, at this time, she was old enough to form detailed memories.
Aisha and Muhammad's marriage was consummated in 2 AH, as per Sahih al-Bukhari 3896 (sunnah.com), which was 11 years later, contradicting their marriage being consummated when she was 9.
I want to fact-check this.
Question: Does Aisha witnessing her father's migration to Abyssinia imply she could not have consummated her marriage at age 9?
