📖Srimad Bhagavatam 5.26.15
If a person deviates from the path of the Vedas in the absence of an emergency, the servants of Yamarāja put him into the hell called Asi-patravana, where they beat him with whips. When he runs hither and thither, fleeing from the extreme pain, on all sides he runs into palm trees with leaves like sharpened swords. Thus injured all over his body and fainting at every step, he cries out, “Oh, what shall I do now! How shall I be saved!” This is how one suffers who deviates from the accepted religious principles.
Brahma Purana 106:136
There is a hell named Atratiṣṭha. It contains putrescent urine and faeces. Those who censure Smṛtis and the Vedas fall into it with faces downwards.
Punishment in Hinduism if anyone reject the vedas according to this verse people of all the different religions including the Hindus who are rejecting vedas are all Kaffir so Yamarāja will put them into hell.
