Sahih Muslim , Book 39, Hadith 11 (In-Book) ⓘ
'A'isha reported that a group of Jews came to Allah's Messenger and sought his audience and said: As-Sam-u-'Alaikum. A'isha said in response: As-Sam-u-'Alaikum (death be upon you) and curse also, whereupon Allah's Messenger 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.
وَحَدَّثَنِي عَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، - وَاللَّفْظُ لِزُهَيْرٍ - قَالاَ حَدَّثَنَا سُفْيَانُ، بْنُ عُيَيْنَةَ عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتِ اسْتَأْذَنَ رَهْطٌ مِنَ الْيَهُودِ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالُوا السَّامُ عَلَيْكُمْ . فَقَالَتْ عَائِشَةُ بَلْ عَلَيْكُمُ السَّامُ وَاللَّعْنَةُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " يَا عَائِشَةُ إِنَّ اللَّهَ يُحِبُّ الرِّفْقَ فِي الأَمْرِ كُلِّهِ " . قَالَتْ أَلَمْ تَسْمَعْ مَا قَالُوا قَالَ " قَدْ قُلْتُ وَعَلَيْكُمْ " .
