Hadith 6:1083
Abdullah ibn Numayr narrated to us, Uthman ibn Hakim narrated to us, from Amr al-Ansari, from Umm Sulaym bint Milhan—and she is the mother of Anas—that she heard the Prophet, may God bless him and grant him peace, saying: "There are no two Muslims who have three of their children die before they reach the age of puberty, except that God will cause them both to enter Paradise by the grace of His mercy."
حدثنا عبد الله بن نمير حدثنا عثمان بن حكيم عن عمرو الأنصاري عن أم سليم بنت ملحان وهي أم أنس أنها سمعت النبي صلى الله عليه وسلم يقول ما من مسلمين يموت لهما ثلاثة من أولاد لم يبلغوا الحنث إلا أدخلهما الله الجنة بفضل رحمته
