"When I wanted to give pledge to the Messenger of Allah, I said: 'O Messenger of Allah, women helped me (in wailing for the dead) during the Jahiliyyah; shall I go and help her (in wailing) and then come to you and give you my oath of allegiance?' He said: 'Go and help her.' So I went and helped her, then I came, and gave my pledge to the Messenger of Allah." (Using translation from Nasāʾī 4179)  

أَنْ أُبَايِعَ رَسُولَ اللهِ ﷺ قُلْتُ يَا رَسُولَ اللهِ إِنَّ امْرَأَةً أَسْعَدَتْنِي فِي الْجَاهِلِيَّةِ فَأَذْهَبَ فَأُسْعِدُهَا ثُمَّ أَجِيئُكَ فَأُبَايِعُكَ قَالَ «اذْهَبِي» فَذَهَبْتُ فَسَاعَدْتُهَا ثُمَّ جِئْتُ فَبَايَعْتُ النَّبِيَّ ﷺ  

"The Messenger of Allah accepted our pledge that we would not wail (for the dead)." (Using translation from Nasāʾī 4180)  

«أَخَذَ عَلَيْنَا رَسُولُ اللهِ ﷺ الْبَيْعَةَ عَلَى أَنْ لَا نَنُوحَ»
