A Muslim child who dies in a young age i.e. childhood before puberty
(Buloogh) will not be accountable for any of the obligatory worships and duties because obligatories start only after Buloogh. Allah SWT will grant all the
Muslim children the Paradise and also grant them to intercede
(Shafa’at) for their parents. The Hadeeth says : When Muslim children
die, they will be looked after near the Paradise by Lady Sarah, the
wife of Prophet Ibrahim (AS) and when the Angels tell them to enter
Paradise, they will say: We wait for our parents to enter with us.
Children of non Muslim parents will not be punished in the Day of Judgment but will be given full chance to know the true faith and chose.
Wassalaam.
