Is a father's statement to his son that Allah "has not begotten and has not been begotten, and that He is a cosmic entity with no creator" considered a disbelief (kufr), and is an ignorant person excused for uttering such words?

The questioner must refrain from delving deeply into issues of takfir (declaring someone an apostate), as this is essential for those afflicted with waswas (obsessive whispers).

The father did not err in his words, nor should he be declared an unbeliever. Surat Al-Ikhlas was revealed as an answer to those who asked about Allah's lineage and attributes.

The father's statement, "a cosmic thing that has no creator," is unobjectionable. Allah Almighty can indeed be described as a "thing" (shay'), and "cosmic" (kawni) has a valid interpretation, meaning absolute, general existence. His father intended that Allah Almighty's existence was not preceded by non-existence and was not caused.
