The claim that children under the age of seven are prevented from entering the mosque because they disturb the worshippers

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on preventing children under the age of seven from entering the mosque on the claim that they disturb the worshippers? And how do we reconcile this with the narrated hadiths regarding al-Hasan and al-Husayn, that they used to enter the mosque and come to the Prophet (peace and blessings be upon him)?

Answer:
If they are harming the worshippers, they are prevented, or if they are being bad to the mosque, playing, and screaming, they are prevented. Harm is prevented; there is no harm and no reciprocating harm. Did al-Hasan and al-Husayn play in the mosque, scream, and harm the worshippers? No, rather they came to their grandfather (peace and blessings be upon him), so no harm came from them. Yes.
