Islam and rights of parents

I was going through some question and answers in Islamhelpline and I came across this question pertaining to parents. I am posting a small extract from the entire post which tell us children on how to react to the parents.

Allah says in the Holy Quran Chapter 17 Surah Bani Israel verses 23-24:

"Your Lord has enjoined the following: You should not worship anyone but Him Alone! Treat your parents with great kindness; if either or both of them attain old age, do not even say ‘uff’ to them; nor rebuke them; but speak to them kind words. Treat them with humility and tenderness and pray, “O our Lord, be merciful to them, just as they brought me up with kindness and affection in my childhood.”

If one (Allah forbid) finds one’s parents enraged upon them for any reason whatsoever, absolutely regardless of who is at fault, or who started the argument or disagreement…….the absolute first thing they should do is in extreme humility and politeness seek their forgiveness, and staying within the boundaries of Allah Subhanah, strive their utmost to appease their rage. If their anger, even if one’s parents were to say bad or abusive things to their children, it would be the duty of the child to humbly listen and absorb whatever they might choose to say without as much as building a frown upon their forehead!!!! Such is the level of humility and tenderness and kindness expected from an off-spring in regards to their parents in Islam. That would be akin to piety and righteousness on the part of the child in the Sight of Allah Subhanah.

If one trusts, obeys, and follows the guidance and commands of Allah and His Messenger (saws), one can be assured of never ever being misled; but if one believes, obeys and follows any other guidance, other than that of Allah and His Messenger (saws), one can be assured of being led astray. "
