Narrated `Aisha:
حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ ، عَنْ هِشَامٍ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم " رَأَيْتُكِ فِي الْمَنَامِ يَجِيءُ بِكِ الْمَلَكُ فِي سَرَقَةٍ مِنْ حَرِيرٍ فَقَالَ لِي هَذِهِ امْرَأَتُكَ. فَكَشَفْتُ عَنْ وَجْهِكِ الثَّوْبَ، فَإِذَا أَنْتِ هِيَ فَقُلْتُ إِنْ يَكُ هَذَا مِنْ عِنْدِ اللَّهِ يُمْضِهِ " .
Allah's Messenger (ﷺ) said (to me), "You were shown to me in a dream. An angel brought you to me, wrapped in a piece of silken cloth, and said to me, 'This is your wife.' I removed the piece of cloth from your face, and there you were. I said to myself. 'If it is from Allah, then it will surely be.' "
