Jainism ke anusar, raat ke poshad (sunset ke baad) paani peena nishedh hai. Acharang Sutra aur anya Jain agamon mein yah spasht kaha gaya hai ki sunset ke baad kisi bhi prakar ka jal, bhojan ya dudh adi nahi lena chahiye. Iska mukhya karan ahimsa aur sanyam hai, kyunki raat ko paani mein jeev (sukshm jeev, bacteria adi) ki sankhya badh jaati hai, aur ise peene se anek jeevon ki himsa hoti hai.

Isliye, Jain dharm ke anusar, raat ke poshad mein paani peena uchit nahi hai.
