The above mentioned tradition has also been narrated by Ibn 'Abbas to the same effect through a different chain of transmitters. This version adds:
He (the Prophet) thought that women could not hear (his sermon). So he went to them and Bilal was in his company. He gave them exhortation and commanded them to give alms. Some women put their ear-rings and other their rings in the garment of Bilal.

حَدَّثَنَا مُسَدَّدٌ، وَأَبُو مَعْمَرٍ عَبْدُ اللَّهِ بْنُ عَمْرٍو قَالاَ حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ أَيُّوبَ، عَنْ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ، بِمَعْنَاهُ قَالَ فَظَنَّ أَنَّهُ لَمْ يُسْمِعِ النِّسَاءَ فَمَشَى إِلَيْهِنَّ وَبِلاَلٌ مَعَهُ فَوَعَظَهُنَّ وَأَمَرَهُنَّ بِالصَّدَقَةِ فَكَانَتِ الْمَرْأَةُ تُلْقِي الْقُرْطَ وَالْخَاتَمَ فِي ثَوْبِ بِلاَلٍ .
