Abu Saeed Khudri reported,

A woman came to the Messenger of Allah ﷺ and said, "Messenger of Allah, Some men have taken away your teachings. Set aside for us a day from yourself when we may come to you, and you will teach us from what Allah has taught you."He said, "Gather on such-and-such a day at such-and-such a place."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 three of her children before her except that they will be a shield for her from the Fire."A woman among them asked, "Messenger of Allah, or two?"She repeated it twice.Then he said, "And two, and two, and two."

عن أبي سعيد

جاءت امرأة إلى رسول الله ﷺ فقالت يا رسول الله ذهب الرجال بحديثك فاجعل لنا من نفسك يوما نأتيك فيه تعلمنا مما علمك الله فقال اجتمعن في يوم كذا وكذا في مكان كذا وكذا فاجتمعن فأتاهن رسول الله ﷺ فعلمهن مما علمه الله ثم قال ما منكن امرأة تقدم بين يديها من ولدها ثلاثة إلا كان لها حجابا من النار فقالت امرأة منهن يا رسول الله أو اثنين قال فأعادتها مرتين ثم قال واثنين واثنين واثنين
