عن أنس رضي الله عنه
قال: قال رسول الله صلى الله عليه وسلم: «ما من مسلم يموت له ثلاثة لم يبلغوا الحنث إلا ادخله الله الجنة بفضل رحمته إياهم»
The Messenger of Allah (sallallahu alayhi wa sallam) said, “Any Muslim who loses three children before they reach the age of maturity, will be granted Jannah by Allah, the Exalted, out of His Mercy for them.”.
