Yaseen - 36:22
Why should I not serve the One who created me, to Him you will return.
The believers are aware that they will return to Allah:
The Heights/7:124
I will cut off your hands and your feet crosswise and then I will hang you all!
The Heights/7:125
"They said: "We shall return to our Lord."
The Ornaments of Gold/43:13
"That you may ride on them, and when you are on them, you may think of the favor of your Lord upon you and say: "Glory be to Him Who has given this to our command. We could not have controlled them on our own."
The Ornaments of Gold/43:14
And we shall return to our Lord at the end.
The Companies/39:9
"What do you say to one who prostrates himself at night and stands up and meditates and is conscious of the Hereafter and hopes for the mercy of his Lord? Say, "Are those who know and those who do not know the same?"Only those who have understanding take admonition."
The Believers/23:60
Those who give knowing that they will return to their Lord,
The Man/76:8
They feed the poor, the orphan and the captive with their favorite food.
The Man/76:9
We feed you for the sake of Allah. We do not expect from you anything in return or thanks.
The Man/76:10
We fear from our Lord for a Day that will be a grim and troublesome Day.
The Woman Who Is Examined/60:4
"There is a good example for you in Abraham and those who were with him. Those who were with him said to their people, "We are far from you and those whom you serve besides Allah. We do not know you. There is eternal enmity and hatred between us and you until you believe in Allah ALONE. Except that Abraham´s words to his father, "I will pray for your forgiveness, but I cannot protect you against anything from Allah"(as a mistake). "Our Lord, to You we trust, to You we turn, and to You we shall return."
