Mukhtasar Sahih Bukhari — Hadith 1592

Narrated from Ummul Momineen Aisha Siddiqa (may Allah be pleased with her) that the Prophet Muhammad (peace be upon him) said to her: "I saw you twice in a dream, that you were wrapped in a piece of silk, and it was said to me (by someone), 'This is your wife.' When I uncovered it, it was you inside. I said (in my heart), 'If this is from Allah, then Allah will surely fulfill it.'"
