when the Messenger of Allah accepted the women's oath of allegiance, he accepted their pledge that they would not wail (over the death). They said: "O Messenger of Allah, there are women who helped us to mourn during the Jahiliyyah should we help them to mourn?" The Messenger of Allah said: "There is no helping to mourn in Islam." (Using translation from Nasāʾī 1852)
أَنَّ رَسُولَ اللهِ ﷺ أَخَذَ عَلَى النِّسَاءِ حِينَ بَايَعَهُنَّ أَنْ لَا يَنُحْنَ فَقُلْنَ يَا رَسُولَ اللهِ إِنَّ نِسَاءً أَسْعَدْنَنَا فِي الْجَاهِلِيَّةِ أَفَنُسْعِدُهُنَّ؟ فَقَالَ رَسُولُ اللهِ ﷺ «لَا إِسْعَادَ فِي الْإِسْلَامِ»
