Al-Hadid · 57:21

21. O people! Hasten towards good deeds i.e. repentance and other actions, through which you will achieve forgiveness for your sins. You will also acquire through them a Paradise the width of which is the width of the heavens and the earth; Allah has prepared this Paradise for those who bring faith in Him and His messengers. That reward is a favour of Allah that He grants whichever of His servants He wishes; He (may He be glorified) is the bestower of great favours to His believing servants.
