ما هو الدليل على أن الولد الفاسد يجر لأهله اللعنة؟

There is no evidence that a corrupt child brings a curse upon their parents, except for what is stated in the Hadith: "Indeed, among the greatest major sins is for a man to curse his parents." This was explained as a man insulting another's father, causing that person to insult his father in return, or insulting his mother, causing that person to insult his mother in return. This implies that a child can be a cause for curses to be directed at their parents.
