In case anyone amongst you sees the sad demise of three children of (hers) and she resigns herself to the will of God hoping to get reward, she would be admitted to Paradise. A woman from amongst them said: Messenger of Allah, even if they (the children who die) are two. Thereupon, he (the Holy Prophet, ) said: Even if they are two. (Using translation from Muslim 2632c)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِنِسْوَةٍ مِنَ الْأَنْصَارِ لَا يَمُوتُ لِإِحْدَاكُنَّ ثَلَاثَةٌ مِنَ الْوَلَدِ فَتَحْتَسِبَهُمْ إِلَّا دَخَلَتِ الْجَنَّةَ فَقَالَتِ امْرَأَةٌ أَوِ اثْنَيْنِ يَا رَسُولَ اللهِ؟ قَالَ أَوِ اثْنَيْنِ
