Why do children reap the fruits of their parents? And what is the interpretation of the Hadith: "Every body that has been nourished by unlawful means, the Fire is more befitting for it"?

The question "Why do children reap the fruits of their parents' actions?" is unclear and needs clarification regarding its intended meaning. As for the Hadith narrated by Jabir ibn Abdullah, it is authentic and warns against evil rulers. Whoever believes them and aids them in their injustice is not from the Prophet (peace be upon him) and will not be granted access to the Basin (of Kawthar). However, whoever does not do so is from him and will be granted access to the Basin. The Hadith also mentions that prayer is a sacrifice, fasting is a shield, and charity extinguishes sin. It further states that every flesh nourished by unlawful earnings is more deserving of the Fire, meaning that whoever accustomed himself to eating unlawful things until his body grew from it, then Hellfire is more deserving of him. People are of two types: one who sells himself and dooms his neck, and one who buys himself and frees his neck.
