(35) باب الرِّفْقِ فِي الأَمْرِ كُلِّهِ
Narrated `Aisha:
(the wife of the Prophet) A group of Jews entered upon the Prophet (ﷺ) and said, "As-Samu-Alaikum." (i.e. death be upon you). I understood it and said, "Wa-Alaikum As-Samu wal-la'n. (death and the curse of Allah be Upon you)." Allah's Messenger (ﷺ) said "Be calm, O `Aisha! Allah loves that on, should be kind and lenient in all matters." I said, "O Allah's Messenger (ﷺ)! Haven't you heard what they (the Jews) have said?" Allah's Messenger (ﷺ) said "I have (already) said (to them) "And upon you ! "
