Abu Saeed Khudri reported,
A woman came to the Messenger of Allah ﷺ and said, "Messenger of Allah, the men have taken all your teaching for themselves. Set aside a day for us when we may come to you, so you can teach us what Allah has taught you."He said, "Gather on such and such a day."So they gathered, and the Messenger of Allah ﷺ came to them and taught them from what Allah had taught him. Then he said, "There is no woman among you who sends ahead of her three children but they will be a shield for her from the Fire."One of the women asked, "And two, and two, and two?"The Messenger of Allah ﷺ replied, "And two, and two, and two."

Sahihعن أبي سعيد الخدري، قال
جاءت امرأة إلى رسول الله ﷺ فقالت: يا رسول الله، ذهب الرجال بحديثك، فاجعل لنا من نفسك يوما نأتينك فيه، تعلمنا مما علمك الله. فقال: اجتمعن يوم كذا وكذا. فاجتمعن فأتاهن رسول الله ﷺ، فعلمهن مما علمه الله، ثم قال: ما منكن من امرأة تقدم بين يديها من ولدها ثلاثة إلا كانوا لها حجابا من النار. فقالت امرأة منهن: واثنين، واثنين، واثنين؟ فقال رسول الله ﷺ: واثنين، واثنين، واثنين.
Narrated by Bukhari in the Book of Knowledge (101), and Muslim in the Book of Righteousness and Kinship Ties (2633), both from the route of Ibn Asbahani, from Abu Salih, from Abu Saeed, as related above, and the wording is that of Muslim.A note of benefit, Abu Abbas Qurtubi said, "This hadith indicates that the leader may teach women what they need to know regarding matters of their religion, and that he may set aside a day for them alone, either in the masjid or in some similar setting, so long as being alone with them can be trusted... The hadith also indicates the merit of the women of that time, and how eager they were for knowledge, and to hear hadith from the Messenger of Allah ﷺ. As Ayesha 
said, "How excellent were the women of the Ansar, shyness never prevented them from seeking understanding of the religion."" End of quotation, in summary.
