I guess also child has a natural tendency towards the mother I believe. Islam is a package. Package that involves islamic parenting as well.
Once this is in, everything is Alhamdulilah.
the child obeys the mother because from young, they were always together.
as compared to the father who is always outside working. This is where the mother needs to explain to the child that the father is outside working hard for the family etc.
And the father has to show that despite working hard, he tried his best to spend time with the child.
“Listen to your father, he means well” this continuous words, and hopefully the child gets the idea.
If the father is doing something wrong, no good reason that the child to obey the father. Especially if the father oversteps the boundary.
Even so for those situation, Islam does not teach us to be rude to parents.
Things happen for a reason.
If the mother is giving good advice, doing the right things, giving proper islamic advise to the child.
If the child obeys more than the father, then i see no issues in that matter. There is a hadith mention that the prophet mention mothers 3 times. as opposed to father.
That shows the importance.
Don’t worry about it. InshaAllah this negative perceptions will go away.
