Book Number: 008 / Hadith Number: 3312
'A'isha (Allah be pleased with her) reported: Allah's Messenger (may peace be upon him) contracted marriage with me in Shawwal and took me to his house as a bride during Shawwal. And who among the wives of Allah's Messenger (may peace be upon him) was dearer to him than I, and' A'isha liked that the women (of her family) should enter the houses as brides during the month of Shawwal.
