Surah Hud, Verse 3:
وَأَنِ اسْتَغْفِرُوا رَبَّكُمْ ثُمَّ تُوبُوا إِلَيْهِ يُمَتِّعْكُم مَّتَاعًا حَسَنًا إِلَىٰ أَجَلٍ مُّسَمًّى وَيُؤْتِ كُلَّ ذِي فَضْلٍ فَضْلَهُ وَإِن تَوَلَّوْا فَإِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ كَبِيرٍ

And (commanding you): "Seek the forgiveness of your Lord, and turn to Him in repentance, that He may grant you good enjoyment, for a term appointed, and bestow His abounding Grace to every owner of grace (i.e. the one who helps and serves needy and deserving, physically and with his wealth, and even with good words). But if you turn away, then I fear for you the torment of a Great Day (i.e. the Day of Resurrection).

Verse 4:
إِلَى اللَّهِ مَرْجِعُكُمْ وَهُوَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ

To Allah is your return, and He is Able to do all things."
