Could a Sotapanna reject to give if asked and has? What does one here think: Is a person, having reached the path, able, would he, reject a request of something material, incl. strength and effort in material spheres, if he could share?

In what cases, if he could reject, would he?

(Note: not given for trade, exchange, stacks or entertainment that binds here in this wheel, but as a tiny door out)

I may have missed it, but i have yet to find something in buddhism that says we should give or agree on something that will be harmful to ourselves (as well as what is harmful to others, of course).

I'm not sure there are any hard rules. It seems that it depends on the situation. I hope someone who knows the sutras better than me could chime in on this.
