Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
A woman came to the Messenger of Allah ﷺ and said: "O Messenger of Allah! Only men benefit from your talks, so please fix a day for us, to teach us the knowledge which Allah has taught you." The Messenger of Allah ﷺ fixed a day and directed them to assemble. When they gathered, the Prophet ﷺ went to them and taught them what Allah had taught him. He ﷺ then said, "Any woman of you whose three children die (in infancy) they will be a guard for her against Fire (of Hell)." One of the women asked: "What if she loses two?" The Messenger of Allah ﷺ replied, "Even two."

[Al-Bukhari and Muslim].

وعن أبي سعيد الخدري رضي الله عنه قال: جاءت امرأة إلي رسول الله ﷺ ، فقالت: يا رسول الله ذهب الرجال بحديثك، فاجعل لنا مننفسك يوماً ناتيك فيه تعلمنا مما علمك الله، قال: “اجتمعن يوم كذا وكذا” فاجتمعن، فأتاهن النبي ﷺ فعلمهن مما علمه الله، ثم قال: "ما منكن من امرأة تقدم ثلاثة من الولد إلا كانوا لها حجاباً من النار" فقالت امرأة: واثنين؟ فقال رسول الله ﷺ “واثنين” ((متفق عليه)).
