That the Prophet ﷺ said to her, "You have been shown to me twice in my dream. I saw you pictured on a piece of silk and some-one said (to me). 'This is your wife.' When I uncovered the picture, I saw that it was yours. I said, 'If this is from Allah, it will be done." (Using translation from Bukhārī 3895)
"أُرِيتُكِ في المنامِ مرَّتينِ يحْمِلُك الملكُ في سَرَقَةِ من حريرٍ فيقولُ: هذه امرأتُك فأكشفُ عنها, فإذا هي أنتِ فأقولُ: إنْ يكنْ هذا من عندِ اللهِ يُمْضِهِ" .
