Losing three children
The Prophet (sal Allahu alaihi wa sallam) 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.”
[Sahih Al-Bukhari and Muslim]
(Allah’s Oath here refers to His saying (interpretation of the meaning): “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)
On the Day of Resurrection all humans, believers and disbelievers, will have to cross the “Sirat or Bridge” set over the Hell.
The Believers will cross it in the twinkling of an eye according to their respective deeds done in the world. Some will cross it with the speed of lightning and the air, some like birds and some like fine horses, and others like riding-animals.
All of them will cross the Bridge, some harmed and some unharmed. Some will fall into Hell but will later be removed from it through the Prophet’s intercession.
However, the non-believers will not be able to cross it and all of them will land in Hell. The believer who loses three children and patiently endures this affliction, and anticipates Allah’s reward in the Hereafter, will also be bound to cross the Bridge in deference to the Divine determination.
And Allah knows best!
