31.1 Allah is the granter of forgiveness
He is the One that accepts repentance from His servants
and forgives sins: and He knows all that you do.
Ch 42: V 25
31.2 Never despair of Allah’s mercy
Say: “O My servants who have transgressed against
their souls! Despair not of the Mercy of Allah, for Allah
forgives all sins: for He is Oft-Forgiving, Most Merciful”.
Ch 39: V53
31.3 Associating others with Allah is unforgivable
unless one amends
Allah forgives not that partners should be set up with
Him; but He forgives anything else, to whom He please;
to set up partners with Allah is to devise a great sin
indeed.
Ch 4: V 48
31.4 Sins in ignorance
When those come to you who believe in our signs, say:
“Peace be on you: your Lord has inscribed for Himself
(the rule of) mercy: Verily, if any of you did evil in
ignorance, and thereafter repented, and amended (his
conduct), Lo! He is Oft- Forgiving, Most Merciful.
Ch 6: V54
31.5 Never repeat the same sin
And those who, having done something to be ashamed
of, or wronged their own souls, earnestly bring Allah to
mind, and ask for forgiveness for their sins,- and who
can forgive sins except Allah? - And they never persist
knowingly in (the wrong) they have done.
Ch 3: V135
31.6 Change of behaviour is counted as true
repentance
Unless he repents, believes, and works righteous
actions, for Allah will change the evil of such persons
into good, and Allah is Oft-Forgiving, Most Merciful,
And whoever repents and does good has truly turned
to Allah with true repentance.
Ch 25: V70 - 71
