[Machine] I came with my mother Barirah bint Al-Harith Al-Atwariyyah to pledge allegiance to the Prophet ﷺ while he was striking a deal with a group of immigrant women. He was leaning against a wall and took a pledge from us that we would not associate partners with Allah. When we confirmed our commitment and extended our hands to pledge allegiance, he said, "I do not shake hands with women." So he made dua for us and that was our pledge.  

جِئْتُ أَنَا وَأُمِّي بَرِيرَةُ بِنْتُ الْحَارِثِ الْعَتْوَارِيَّةُ فِي نِسَاءٍ مِنَ الْمُهَاجِرَاتِ فَبَايَعْنَا النَّبِيَّ ﷺ وَهُوَ ضاربٌ عَلَيْهِ قُبَّةً بِالْأَبْطَحِ فَأَخَذَ عَلَيْنَا أَنْ لَا نُشْرِكَ بِاللهِ شَيْئًا الْآيَةَ فَلَمَّا أَقْرَرْنا وبَسَطْنا أَيْدِينَا لِنُبَايِعَهُ قَالَ «إِنِّي لَا أَمَسُّ أَيْدِي النِّسَاءِ» فَاسْتَغْفَرَ لَنَا وَكَانَتْ تِلْكَ بِيعَتَنَا
