The rights of parents are great indeed. Allaah mentions parents’ rights in conjunction with His own rights in many verses, for example, when He says (interpretation of the meaning):
“Worship Allaah and join none with Him (in worship); and do good to parents”
“And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents”
“And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents. Unto Me is the final destination”
Our Parents have such a high stauts in our eyes, especially the mother:
A man came to the Prophet and said, ‘O Messenger of God! Who among the people is the most worthy of my good companionship? The Prophet said: Your mother. The man said, ‘Then who?’ The Prophet said: Then your mother. The man further asked, ‘Then who?’ The Prophet said: Then your mother. The man asked again, ‘Then who?’ The Prophet said: Then your father. (Bukhari, Muslim).
So we have to bear in mind to listen and to obey our parents, doing whatever they would like us to do, (apart from that which is haraam of course).
Your parents have brought you up in this world, your Father working hard earning money, so you can eat, have clothes on your back and shelter over your head. Your mother carrying you for nine months, then having to look after you, wake up in the night for you, breastfeed you.. and the list goes on.
Be grateful you have parents that looked after you and loved you. Some people don’t even have that much.
If they have passed away, make Dua for them if they were muslim but misguided and pay any debts they have/had.
If they are still with you, guide them to the right and be sincere towards them.
And last of all, obey your parents. They have done so much for you, and this is the least you could do for them.
