Young marriage age controversy
The age of Aisha at marriage is an extremely contentious issue. On the one hand, there are several hadiths which are said to have been narrated by Aisha herself, which claim that she was six or seven years old when betrothed and nine when the marriage was consummated. On the other hand, calculations based on information found in an early Muslim chronicler, Ibn Ishaq, indicate that Aisha was at least fourteen to sixteen years old, thus past the age of puberty. Other hadiths suggest that Aisha may have been nineteen or twenty years old when she married.
