I heard a story about this man who had a farther who was not religious (since he had survived the Holocaust) and he became a millionaire when he came to the USA.
He had 2 sons, 1 was not frum like his farther, 1 became frum.
After he died they were to divide the money (about $100 million), but on condition that the farther would be cremated according to his wishes.
The frum son would not take the $50 milllion and made a deal with the not frum son that he would give his farther a proper burial.
The non frum son was so amazed by this, he gave the farther a proper burial, and became frum.
