touched by the lecture in Al-Furqan mosque after Zuhr. - true, we might try and struggle to be good Muslims, but it will count to nothing as we often let (what we assume) the smallest of things runs under our nose while it is the biggest of thing after Allah, birrul walidain that is.
Waqadla rabbuka alla ta’budu illa iyyahu wabil walidaini ihsana imma yablughanna indakalkibara ahaduhuma aukilahuma fala taqullahuma uf wala tanharhuma waqullahuma qaulan karima, wahfidlahuma janahadldlulli minarrahmati waqurrabirhamhuma kama rabbayani shaghira” ([17.23]
Your Lord has ordered you to worship none except Him, and to be good to your parents. If either or both of them attain old age with you, do not say: “Uff”, nor rebuke them, but speak to them with words of respect.
birrul walidain (doing good to parents) in fact, comes straight after Allah (worship none except Him, and to be good to your parents). 'uququl walidain (hurting your parents even 'uff') is kibarul kibr, one of the biggest sins of all sins, right after shirk (as what ulama' agreed upon).
we might do zina or not praying or drinking or swearing or telling lies or not completing the amanah and think we might get away with it because there's no quick punishment. it is not the case with 'uququl walidain, the punishment of 'uququl walidain is quick and it's settled in this dunya and there are more punishments reserved for us in the akhirah (on top of our sins of committing zina, not praying, drinking, swearing, telling lies etc)
beware that we will go bankrupt on yaumulqiyamah even though we worked hard in our ibadah in this dunya if we do 'uququl walidain, our WHOLE ibadah will vanish on that day if our parents are not pleased with us, even if there is a slightest 'terasa hati', as the blessings of Allah lies in our parents hands.
I urge myself and you to just go and say to our parents, "mom dad, sorry for everything I've done..", for that (awkward) moment might save us from hellfire later on.
