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)
أَخَذَ النَّبِيُّ ﷺ عَلَى النِّسَاءِ حِينَ بَايَعَهُنَّ أَنْ لَا يَنُحْنَ فَقُلْنَ يَا رَسُولَ اللهِ إِنَّ نِسَاءً أَسْعَدْنَنَا فِي الْجَاهِلِيَّةِ أَفَنُسْعِدُهُنَّ فِي الْإِسْلَامِ؟ فَقَالَ النَّبِيُّ ﷺ لَا إِسْعَادَ فِي الْإِسْلَامِ
