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."

At length when he reaches the age of full strength and attains forty years he says "O my Lord! grant me that I may be grateful for Thy favor which Thou hast bestowed upon me and upon both my parents and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam."
16. Such are they from whom We shall accept the best of their deeds and pass by their ill deeds: (they shall be) among the Companions of the Garden: a promise of truth which was made to them (in this life).
17. But (there is one) who says to his parents "Fie on you! Do ye hold out the promise to me that I shall be raised up even though generations have passed before me (without rising again)? " And they two seek Allah`s aid (and rebuke the son): "Woe to thee! Have Faith! For the promise of Allah is True." But he says "This is nothing but tales of the ancients!"
Allah says in the Holy Quran Chapter 6 Surah Anaam verse 151:
