One of the few ghazals sung by Lata Mangeshkar. Written by Ghalib.
Ye hum jo *hijr mein diwaar-o-dar ko dekhte hein
Kabhi *sabaa ko kabhi *naamaabar ko dekhte hein
Woh aaye humaare ghar pe Khuda ki kudrat hai
Kabhi hum unko kabhi apne ghar ko dekhte hein
Nazar lage ka kahin uske *dast-o-baazu ko
Ye log kyon mere zakhm-e-jigar ko dekhte hein
- Mirza Ghalib
*hijr means separation (from beloved)
*sabaa means breeze
*naamaabar means messenger
*dast means hands
The last sher is one of the best I have ever read.
