1a] He gave charity on the basis that by doing so all his sins would be forgiven

1a]
accordance with sharee'ah, and whatever there is of innovation in
itmay be forgiven on the basis that he tried to work out what was
correct or he was following someone and thus may be excused. The same
applies to whatever is mentioned of benefits of certain actions;
whatever benefit is gained may be because ofwhatever in his action was
in accordance with sharee'ah, such as fasting, dhikr, reading Qur'aan,
bowing, prostrating and good intentions in worshipping and obeying
Allah and calling upon Him. And whatever it included of things that
aredisliked in sharee'ah may be forgiven by Allah because he based his
action of what he thoughtwas best or he followed the example of
someone else. And this is applicableto everything that may bementioned
of the benefitsof some innovated actionsthat are disliked, but
nevertheless this possible benefit does not cancel out the fact that
it is disliked and forbidden, and one should do what is prescribed and
has no innovation in it.

And Allah knows best.
