Is it undutifulness to parents for a son to supplicate for his mother more than for his father?

Question : This questioner, Tariq Hassan, is Egyptian and resides in Makkah al-Mukarramah. He says: Honorable Shaykh, I give my mother a great deal of supplication, but I give my father only a little, and I often forget to supplicate for him. Is that undutifulness to him, knowing that I love him very much? I hope for an answer from the Honorable Shaykh. May Allah reward you with good.

Answer : It is best for a person to make du'a' for both of his parents, saying: "O Allah, O Allah, forgive my father, O Allah, " and the like. This is the best. And if he gives his mother preference over his father, there is no blame on him for that, because the mother is more deserving of good companionship than the father, as that came in the hadith from the Messenger
