As-Sam-u-'Alaikum. A'isha said in response: As-Sam-u-'Alaikum (death be upon you) and curse also, whereupon Messenger of Allah ﷺ said: 'A'isha, verily Allah loves kindness in every matter. She said: Did you bear what they said? Thereupon he said: Did you not hear that I said (to them): Wa 'Alaikum. (Using translation from Muslim 2165a)
دَخَلَ رَهْطٌ مِنَ الْيَهُودِ عَلَى رَسُولِ اللهِ ﷺ فَقَالُوا السَّامُ عَلَيْكُمْ فَفَهِمْتُهَا فَقُلْتُ عَلَيْكُمُ السَّامُوَاللَّعْنَةُ فَقَالَتْ فَقَالَ رَسُولُ اللهِ ﷺ مَهْلًا يَا عَائِشَةُ إِنَّ اللهَ ﷻ يُحِبُّ الرِّفْقَ فِي الْأَمْرِ كُلِّهِ قَالَتْ قُلْتُ يَا رَسُولَ اللهِ أَلَمْ تَسْمَعْ مَا قَالُوا؟ فَقَالَ رَسُولُ اللهِ ﷺ فَقَدْ قُلْتُ وَعَلَيْكُمْ
