Musnad Ahmad 1153:1267

Hammad ibn Usamah narrated to us, he said: Hisham informed us, from his father, from Aisha, she said: The Messenger of Allah, may Allah bless him and grant him peace, said to me: "I saw you in a dream twice. I saw a man carrying you in a piece of silk, and he said: 'This is your wife.' So I uncovered it, and behold, it was you. I said: 'If this is from Allah, the Exalted and Majestic, He will bring it to pass.'"
