"Jibrail send (greetings of) Salam to you." She said: "Wa 'alahisalam wa rahmatullah (and upon him be peace and mercy of Allah)." (Using translation from Ibn Mājah 3696)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَهَا إِنَّ جِبْرِيلَ عَلَيْهِ السَّلَام يُقْرِئُكِ السَّلَامَ فَقَالَتْ وَعَلَيْهِ السَّلَامُ وَرَحْمَةُ اللهِ
