ham bane tum bane

Mirza Asadullah Khan Ghalib wrote: ishq par zor nahii.n hai ye vo aatish Gaalib jo lagaa_e na lage aur bujhaa_e na bane.
Anand Bakshi used it in his song
"ham bane tum bane ek duuje ke li_e...ishq par zor nahii.n Gaalib ne kahaa hai isii li_e" from the film Ek Dooje Ke Liye (1981). One of the rare occasions when a poet has been credited in the song itself!
