The ruling on the testimony of a discerning child of disbelievers who has pronounced the two testimonies of faith

The questioner:
The Shaykh said: May Allah inform you, regarding the discerning child of disbelievers who has pronounced the two testimonies of faith, is his testimony accepted or not?

The Shaykh:
One is not declared a Muslim until he reaches puberty, because the child of disbelievers follows the disbelievers, and the child of Muslims follows the Muslims. Therefore, he is not ruled to be a disbeliever or a Muslim until after puberty. That is, regarding his apostasy, he is not ruled to be an apostate until after puberty, as you heard, and he is not ruled to be a Muslim until after puberty.

The questioner:
The case of Shaykh Ahmad (may Allah have mercy on him).

The Shaykh:
Because the default for the children of disbelievers is that they are disbelievers, so they do not depart from this default except by entering Islam after puberty. This is the default for them, unlike the children of Muslims, for whom the default is Islam.
