The preaching (and teaching) of the (religious) knowledge to women by the Imam (Chief)
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَيُّوبَ، قَالَ سَمِعْتُ عَطَاءً، قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ، قَالَ أَشْهَدُ عَلَى النَّبِيِّ صلى الله عليه وسلم ـ أَوْ قَالَ عَطَاءٌ أَشْهَدُ عَلَى ابْنِ عَبَّاسٍ ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ وَمَعَهُ بِلاَلٌ، فَظَنَّ أَنَّهُ لَمْ يُسْمِعِ النِّسَاءَ فَوَعَظَهُنَّ، وَأَمَرَهُنَّ بِالصَّدَقَةِ، فَجَعَلَتِ الْمَرْأَةُ تُلْقِي الْقُرْطَ وَالْخَاتَمَ، وَبِلاَلٌ يَأْخُذُ فِي طَرَفِ ثَوْبِهِ. وَقَالَ إِسْمَاعِيلُ عَنْ أَيُّوبَ عَنْ عَطَاءٍ وَقَالَ عَنِ ابْنِ عَبَّاسٍ أَشْهَدُ عَلَى النَّبِيِّ صلى الله عليه وسلم.
Narrated Ibn 'Abbas: Once Allah's Messenger (ﷺ) came out while Bilal was accompanying him. He went towards the women thinking that they had not heard him (i.e. his sermon). So he preached them and ordered them to pay alms. (Hearing that) the women started giving alms; some donated their ear-rings, some gave their rings and Bilal was collecting them in the corner of his garment.
