Sahih Bukhari Volume 9, Book 87, Hadith Number 139.

Narrated By ‘Aisha : Allah’s Apostle said (to me), “You were shown to me twice in (my) dream. Behold, a man was carrying you in a silken piece of cloth and said to me, “She is your wife, so uncover her,’ and behold, it was you. I would then say (to myself), ‘If this is from Allah, then it must happen.'”
