The Messenger of Allah ﷺ married her when she was six years old, consummated the marriage when she was nine, and passed away when she was eighteen.

Sahihعن عائشة قالت
تزوجها رسول الله ﷺ وهي بنت ست سنين، وبنى بها، وهي بنت تسع، ومات عنها، وهي بنت ثمان عشرة.
Muslim narrated it in the Book of Marriage (1422: 72), through several chains from Abu Muawiya, from Amash, from Ibrahim, from Aswad, from Ayesha, and he mentioned it.His statement, "six years old," and in another narration, "seven years old," can be reconciled by saying that she had completed her sixth year and entered her seventh.She died 
in the year fifty-eight, on the night of Tuesday, seventeen nights into Ramadan, according to the majority. It is also said the year fifty-seven. She was buried at Baqi. Isabah (11593).
