हम दुआ लिखते रहे - Hum Duaa Likhtay Rahay

हम दुआ लिखते रहे - वो दग़ा पढ़ते रहे 
एक नुक़्ते ने महरम से मुजरिम कर दिया 

Hum duaa likhtay rahay - vo daghaa padhtay rahay
Ek nuqtay nay Mehram say Mujrim kar diya 

"I wrote ‘Duaa’ - They read it as Daghaa 
Just one dot turned it from well-wisher into fraudulent"

When writing in Urdu - in Persian or Arabic script - the words Duaa and Daghaa -
Or Mehram and Mujrim are very similar to each other. The difference is only of a dot - called nuqta. 
Placing a dot on top of Duaa makes it Daghaa
and placing a dot underneath Mehram makes it Mujrim -  both conveying opposite meanings.  
One small mistake - one wrong gesture can make a huge difference.

Duaa    -     prayer or a well-wishing thought 
Daghaa  -   deception, deceitfulness
Mehram  -  Well-wisher
Mujrim   -  Criminal, Fraudulent, Offender 

 For those who can read Urdu:

 ہم دعا  لکھتے رہے  -  وو دغا  پڑھتے رہے 
ایک نقطے نے محرم سے مجرم  کر دیا
