Hadith 6:1082
Abu Usama narrated to us, from Abd al-Rahman ibn Yazid, [who said] Qasim narrated to us, from Abu Umamah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "There are no two believers who have three of their children die before they reach the age of puberty, except that Allah will cause them both to enter Paradise by the grace of His mercy toward them."
حدثنا أبو أسامة عن عبد الرحمن بن يزيد حدثنا القاسم عن أبي أمامة قال قال رسول الله صلى الله عليه وسلم ما من مؤمنين يموت لهما ثلاثة من أولاد لم يبلغوا الحنث إلا أدخلهما الله الجنة بفضل رحمته إياهم
