Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : “لا يموت لأحد من المسلمين ثلاثة من الولد لا تمسه النار إلا تحلة القسم" ((متفق عليه))
The Messenger of Allah (ﷺ) said, "A Muslim whose three children die (in infancy) will not be touched by the Fire (of Hell) except for the fulfillment of Allah's Oath."[Al-Bukhari and Muslim].[Allah's Oath here refers to His Ayah: "There is not one of you but will cross over it (Hell)." (19:71) And the crossing will be across the 'Bridge' set over the Hell.]
