Surah An-Nisa Ayahs #17 Translated in English

These are the limits [set by] Allāh, and whoever obeys Allāh and His Messenger will be admitted by Him to gardens [in Paradise] under which rivers flow, abiding eternally therein; and that is the great attainment.

And whoever disobeys Allāh and His Messenger and transgresses His limits - He will put him into the Fire to abide eternally therein, and he will have a humiliating punishment.

Those who commit immorality [i.e., unlawful sexual intercourse] of your women - bring against them four [witnesses] from among you. And if they testify, confine them [i.e., the guilty women] to houses until death takes them or Allāh ordains for them [another] way.

And the two who commit it [i.e., unlawful sexual intercourse] among you - punish [i.e., dishonor] them both. But if they repent and correct themselves, leave them alone. Indeed, Allāh is ever Accepting of Repentance and Merciful.

The repentance accepted by Allāh is only for those who do wrong in ignorance [or carelessness] and then repent soon [after]. It is those to whom Allāh will turn in forgiveness, and Allāh is ever Knowing and Wise.
