And whoever desires the Hereafter and strives for it, with the necessary effort due for it (i.e. does righteous deeds of Allah's obedience) while he is a believer (in the Oneness of Allah - Islamic Monotheism) - then such are the ones whose striving shall be appreciated (thanked and rewarded by Allah).
And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents. If one of them or both of them attain old age in your life, say not to them a word of disrespect, nor shout at them but address them in terms of honour.
And lower to them the wing of submission and humility through mercy, and say: "My Lord! Bestow on them Your Mercy as they did bring me up when I was young."
Your Lord knows best what is in your inner-selves. If you are righteous, then, verily, He is Ever Most Forgiving to those who turn to Him again and again in obedience, and in repentance."
(Surah 17: Al-Isra (The Journey by Night); verses 18-19 - 23-25)
