Noman Bin Bashir Raziallahu Anhu Se Rivayat Hai

K Rasulullah Sallallahu Alaihi Wasallam Ne
Sahaba Karaam (Raziallahu Anhum) Ko Khaberdaar Kertey Hoe Fermaya
Sunlo Badan Main Gosht Ka Ek Tukra Aesa Hai
Jab Woh Durust Ho To Saara Jism Durust Hota Hai
Aur Woh Bigar Jae To Sara Jism Bigar Jata Hai
Yaad Rakho Woh Tukra Insaan Ka Dil Hai

(Sahih Bukhari)
