Have the children of Muslims entered Paradise, and the children of disbelievers the Fire? And will the children of Muslims intercede for their parents who have entered the Fire?

The children of Muslims are in Paradise by scholarly consensus. Abraham and Sarah will care for them until they return them to their parents on the Day of Resurrection, and they will intercede for their parents to enter Paradise. As for the children of polytheists, scholars have differed concerning them, and the most likely opinion is that they are in Paradise, based on the hadith: "The children of polytheists are the servants of the people of Paradise," and based on the hadith of the Prophet's vision (peace be upon him) of Abraham with the children of people and the children of polytheists around him, and based on the Almighty's saying: [And We would not punish until We had sent a messenger]. However, they will not intercede for their parents.
