The Ruling on Undutifulness to Parents and the Repentance of the Undutiful Child

Question:
His second question: He says: Shaykh Salih, what is the ruling on undutifulness to parents? And do I have a repentance?

Answer:
Undutifulness to parents is a major sin among the major sins, and it comes after shirk (associating partners with Allah), just as dutifulness to them comes after obedience to Allah the Exalted. So dutifulness to parents comes after tawhid (the oneness of Allah) (Mighty and Majestic), and undutifulness to them is forbidden, coming after shirk (associating partners with Allah) (Mighty and Majestic). So you must repent to Allah. If the father is present, or the mother is asking for forgiveness from them, improve your treatment of them and be dutiful to them. If they are dead, then you must give charity on their behalf, make du'a' (supplication) for them, and seek forgiveness for them. Yes.
