Dusron ko achchi baaton ka hukm karo magar khud bhi us par amal karo warna.....

Urdu Translation:
Usama bin zaid radi allaho anho se rivayat hai ki Rasoollallah sallallaho alaihey wasallam ne farmaya Qayamat ke din ek shaksh laya jayega phir wo jahannam mein dala jayega uskey pet ki aantein (intestine) bahar nikal aayegi, wo unko liye huye gadhey ki tarah jo chakki peesta hai chakkar lagayega aur jahannam waley uskey paas ekaththey hongey us sey puchengey ki Eh falah kya tu achchi baaat ka hukm nahi karta tha aur buri baat se manaa nahi karta tha ? wo kahega main to aisa karta tha lekin dusron ko achchi baat ka hukm karta tha aur khud (us par amal ) nahi karta aur dusron ko buri baat se manaa karta tha lekin khud us sey baaz na rahta tha.
Sahih Muslim, 7483

English Translation:
Usama b. Zaid Radi Allaho Anho reported: I beard Allah's Messenger (may peace be upon him) as saying: A man will be brought on the Day of Resurrection and thrown in Hell-Fire and his intestines will pour forth in Hell and he will go round along with them, as an ass goes round the mill. stone. The denizens of Hell would gather round him and say: 0, so and so, what has happened to you? Were you not enjoining us to do what was reputable and forbid us to do what was disreputable? He will say: Of course, it is so; I used to enjoin (upon people) to do what was reputable but did not practise that myself. I had been forbidding people to do what was disreputable, but practised it myself.
