The Ruling on the Children of Muslims and Disbelievers in the Hereafter

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: If a child dies, is it permissible for me to specify that he is in Paradise, or is this a general matter and it is not permissible to specify?

Answer:
The people of the period of ignorance (al-fatra); his ruling is that he is among the people of the period of ignorance. This is the child of the disbelievers, who is among the people of the period of ignorance. He follows his family in this world, but his ruling in the Hereafter is that he is among the people of the period of ignorance. As for the child of the believers, this is the ruling of the believers.
