Allah is happy with humble servants who worship Him with dedication and always remember Him especially before any act or any word , and who serve others for the sake of Allah (SWT). Allah is happy with the humble servants who serve and treat their parents nicely. No one can be accepted by Allah if he is bad to his parents. Obey your parents in every matter which goes along with religion and does not contradict any order of Allah (SWT). Treat them nicely and very politely under any circumstance.
More you make your parents happy, the more Allah will be pleased with you.
