user5000: If you knew about a Dhamma practitioner who strongly believes in no reincarnation or post-mortem rebirth what would be your advice to him/her?

user-1: One could "give a talk" like the Buddha gave to the Kalamas.
The Buddha pointed out here, that it is merely risky to relay on people who are not clean and pure in their ways and livelihood. One, an ordinary person, is not able to teach rightly and has his preoccupations.

"And this deluded person, overcome by delusion, his mind possessed by delusion, kills living beings, takes what is not given, goes after another person's wife, tells lies, and induces others to do likewise, all of which is for long-term harm & suffering."

Simply focus on what is skilfully and unskilfully, making clear that one not acting skilful by himself can not be easy a place to relay on, find out by yourself what leads to longterm happiness while searching for approve from the wise and then, end your teaching, after indroducing to the Brahma-Viharas, like him:

"Now, Kalamas, one who is a disciple of the noble ones — his mind thus free from hostility, free from ill will, undefiled, & pure — acquires four assurances in the here-&-now:
"'If there is a world after death, if there is the fruit of actions rightly & wrongly done, then this is the basis by which, with the break-up of the body, after death, I will reappear in a good destination, the heavenly world.' This is the first assurance he acquires.
"'But if there is no world after death, if there is no fruit of actions rightly & wrongly done, then here in the present life I look after myself with ease — free from hostility, free from ill will, free from trouble.' This is the second assurance he acquires.
"'If evil is done through acting, still I have willed no evil for anyone. Having done no evil action, from where will suffering touch me?' This is the third assurance he acquires.
"'But if no evil is done through acting, then I can assume myself pure in both respects.' This is the fourth assurance he acquires.
"One who is a disciple of the noble ones — his mind thus free from hostility, free from ill will, undefiled, & pure — acquires these four assurances in the here-&-now."

Having trained them quite good and eager, they might be able to understand the teachings on Kamma and rebirth later on better.
