Tu hi hai aashiqui
Tu hi awaaragi
Tu hi hai zindagi
Tu hi

btedaa meri
Tu intehaa meri
era jahaan
Tu hi judaa

Tu mere rubaroo
Har shay mein tu hi tu
Tu pehli aarzoo
Tu hi judaa
Tu hi hai aashiqui... hi judaa
Dil ne kahaa tha na tadpega
Phir aaj dil dhadke kyun jaaye
Khwaabon ne tay kiya tha khona
Phir aaj kyun palat woh aaye
Tujhme likha hoon main
Tujhse juda hoon main
Tu mera rog hai
Tue hi dawaa
Tue hi hai aashiqui...Tu hi judaa
Aadhi hai rehguzarAadha hai aasmaanAadhi hai manzileinAadha hai jahaan

Tera hoon jaan leRooh mujhse baandh leBaanhon mein thaam leKar de zindaHar shay mein tu
Chappe chappe mein tuKhwahish mein tuQisse qisse mein tuHar zidd mein tuFikron zikron mein tu

Tue hi hai aashiquiTu hi awaaragiTu hi hai zindagiTu hi judaaTu ibteda meriTu intehaa meriTu hi mera jahaanTu hi judaa
Soundhi si baatein hainRaahat se naate hainRishta sukoon se phir hai judaPhir meethi dhoop haiPhir teri chhaanv haiApni har saans tujhpe doon luta
Rag rag mein tuZarre zarre mein tuNas nas mein tuQatre qatre mein tuTujhme hoon mainMujhme basi hai tu

Poori hai rehguzarPoora hai aasmaanPoori hai zindagiPoora jahaan
Sang tere raastaSadiyon ka waastaPhir se jeene ki ek tu hi wajah
Tujhme likhi hoon mainTujhse judi hAoon mainTu mera rog hai, Tu hi dawaa
Tue hi hai aashiquiTu hi awaaragiHum mauj,
