Outstanding song from film Haqeeqat (1964) by Rafi Sahib. No one can sing this song with so much emotion and pathos.
Music: Madan Mohan
Lyrics: Kaifi Azmi
Raga:

uN uN uN, uN-uN uN, uN uN

main ye sochkar uske dar se uThaa thaa
ke vo rok legi manaa legi mujhko

havaaoN mein lahraataa aataa thaa daaman
ke daaman pakaDkar biThaa legi mujhko

kadam aise andaaz se uTh rahe the
ke aavaaz dekar bulaa legi mujhko

magar usne rokaa
na usne manaayaa
na daaman hi pakaDaa
na mujhko biThaayaa
na aavaaz hi dii
na vaapas bulaayaa
main aahistaa aahistaa baDhtaa hi aayaa
yahaaN tak ke us se judaa ho gayaa main -2
judaa ho gayaa main -4
