Compulsory rights of parents.
Despite the religion of one's parent one has to follow the basic rights of parents.
1. You should never cause them any harm even if they are wrong and commit any excesses. You should always be very polite with them.
2. Have Respect and Honor in your speech while speaking to your parents. Be kind and treat them in the best possible way. Never raise your voice.
3. Obey your parents in everything unless it is not permissible. If you disagree do not disrespect them or belittle them.
4. If your parents need any financial assistance, assist them even if they happen to be non-believers and do so with great humbleness and without showoff or making them feel guilty.
5. Don't look at them with a frown or anger them. Always smile and make them happy.
Respect and honor are parents first right. No matter how wrong a parent is, a child is never to misbehave with his parents. It is considered to be a great sin if one misbehaves or disrespects one's parents.
As the Holy Prophet SAW stated that:
Anas (RA) states that when the Holy Prophet (PBUH) was asked about the grave sins, he said, “
(1) Associating partners with Allah.
(2) Being disobedient & insolent to parents,
(3) to kill a human being without justified reason, and
(4) to become a false witness to a unwitnessed incident”.
We can clearly realize how grave a sin it is by disobeying and misbehaving with one’s parents through this Hadith of the Holy Prophet SAW.
Obedience to parents in light of hadith of Prophet Muhammad (saw)
Hazrat Ibn Abbas narrates from the Prophet that a person whose parents are alive, and he obeys them, listens to and respects them, then Allah will open two doors of paradise for him. But if one of his parents is not happy with him, then Allah will not be happy with him either. Then someone asked the Prophet, “Even if they are oppressors?” The Prophet replied, “Yes, even if they are oppressors.”
This Hadith of the Holy Prophet SAW clearly tells us that even if our parents oppress us and do not let us live freely, we still were not allowed to misbehave with them, and we were supposed to follow their every instruction blindly (as long as is does not contradict the Islamic teachings).
The Greatest Obligatory Act
The Commander of the Faithful (peace be upon him) has said: “Goodness towards (one's) parents is the greatest obligatory act.”
Mizanul Hikmah, Volume 10, Page 709
Better than Jihad
[A person once approached the Messenger of Allah (peace be upon him and his family) and said: “I have an old father and mother, who due to their attachment towards me, are not keen for me to go to Jihad.”]
[Hearing this], the Noble Prophet (peace be upon him and his family) said: “(If such is the case then) Stay with your parents for, by the One in whose control lies my soul, their attachment of one day and one night to you is better than one year of Jihad.”
Biharul Anwar, Volume 74, Page 82
[Ibne `Abbas states:] “I questioned the Messenger of Allah (peace be upon him and his family): Which deed is the most beloved in the eyes of Allah, the Mighty, the Glorious?” He (peace be upon him and his family) replied: “(Offering) prayers at their stipulated times.” I then asked: “Which is the next most beloved deed?” He (peace be upon him and his family) answered: “Goodness towards (one’s) parents.” I asked him again: “After this which is the most beloved act?” He (peace be upon him and his family) said: “Jihad in the way of Allah.”

Looking at them
The Messenger of Allah (peace be upon him and his family) said: “Every righteous child who casts a look of mercy and affection upon his parents shall be granted, for every look of his, rewards equivalent to that of an accepted Hajj.” Those around the Prophet questioned: “O’ Prophet of Allah! Even if he were to look at them a hundred times a day?” The Messenger of Allah (peace be upon him and his family) replied: “Indeed! Allah is the Greatest and Most Kind.”

There are numerous other hadith that are self-explanatory about the blessing and mercy that lie in being kind and loving to one's parents and that will teach us to treat our parents in a much better way.
May Allah guide us all.
