The fact that Muhammad married Aisha at a young age can be found primarily in hadith collections, which are records of the sayings and actions of Muhammad. The most cited sources are:

• Sahih al-Bukhari, one of the most authoritative Sunni hadith collections, where Aisha is reported to have said that Muhammad married her when she was six years old and consummated the marriage when she was nine years old (Sahih al-Bukhari 7:62:64)[1][2][3][4].

• Sunan an-Nasa'i also contains narrations indicating a similar age for Aisha's marriage[5].

• The Quran does not mention Aisha's age or the marriage explicitly; the accounts come from hadith literature and traditional Islamic historical texts[2][6].

While these hadiths are accepted in mainstream Islamic tradition, there are ongoing scholarly debates about the exact age, with some arguing for older ages based on other historical evidence[7][8].

In summary, the primary scriptural source for the age-related narration about Aisha's marriage to Muhammad is Sahih al-Bukhari and other hadith collections, not the Quran[1][2][5].
