Allah Most High has brought human beings into existence. He has made the parents the means of bringing us into this world. Almighty Allah has made parents an embodiment of affection and mercy and has obligated them to raise their children in the proper manner. Children have also been ordered to serve their parents and fulfill the rights due to them. The importance of fulfilling the rights of the parents can be understood with the fact that in the Holy Quran, Almighty Allah has mentioned nice treatment of parents immediately after mentioning His own worship and servitude. It is given in the Holy Quran:
And your Lord has commanded you not to worship anyone other than Allah, and treat parents with benevolence. If either or both of them attain old age in your presence, then do not say even “Ugh” to them, nor reproach them. And always speak to both of them submissively, observing polite manners. And always lower your wings of submissiveness and humility out of soft-heartedness for both of them, and keep supplicating (Allah): O my Lord, have mercy on both of them as they brought me up in (my) childhood (with mercy and clemency). Surah Bani Israil (17:23, 24)
In this verse of the Holy Quran, Almighty Allah has given us 7 orders, 5 of which things that we have to do and 2 of which are things we have stay away from.
