How can I enter Paradise?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

The only way for a person to enter Paradise is to fear Allaah the Almighty, abide by His orders and avoid His prohibitions. Allaah the Almighty Says (what means): {And hasten to forgiveness from your Lord and a garden as wide as the heavens and earth, prepared for the righteous. Who spend [in the cause of Allaah] during ease and hardship and who restrain anger and who pardon the people - and Allaah loves the doers of good; And those who, when they commit an immorality or wrong themselves [by transgression], remember Allaah and seek forgiveness for their sins - and who can forgive sins except Allaah? - and [who] do not persist in what they have done while they know. Those - their reward is forgiveness from their Lord and gardens beneath which rivers flow [in Paradise], wherein they will abide eternally; and excellent is the reward of the [righteous] workers.} [Quran 3:133-136]
