Hamey yeh pata karna tha ki agar hamarey ghar me jo kaamwali kaam karti hai, woh sunni hai. Yeh kapda dhulne ke baad unhey sukhati hai. Lekhin inhey taharat ke bare mai ziyada kuch pata nahi hai, inhey sirf yeh pata hai ki khoon or dusrey aam najasat chizon ko najis karte hai. Lekin inhe yeh nahi pata hai ki ek cheez se dusrey cheez par najasat transfer Hota hai aur inhe yeh bhi thik se nahi pata ki kafir najis hai. Lehaza, kapda sukhatey samey agar yeh kuch najis cheez ko hath lagaye to use yeh nahi pata ki geeley kapdey choone par najasat uspar transfer hota hai. Masalan, agar yeh diwaar ko geeley haton se hath lagaye, toh yeh geeley kapdey ko bina haath dhoye haath lagati hai. Kya phir hamey yeh kapde wapis dhokar sukhana hoga, kyuki ham yeh kapde mei namaz padte hai.
Woh kabhi najis sabzi geeley haton se chookar un haton se geeley kapdey ko chooti hai

1. Nawkrani ko samjha dijye ki najast transfer hoti hai
2. Jab tak apko kisi cheez ke najis hone ka yaqeen na ho to wo apke liye pak hai
