thanks!

Mein pyar ki yaadein dil se mita doongi - I will erase all memories of love from my heart
Mein farz ki khatir sab kuch bhula doongi - For the sake of my duty I will forget it all

Tujhko nibhana hai jo farz hai tera - You to fulfill your duties
Kaise chukaunga mein karz yeh tera - How will I ever repay this debt of yours

Sajde mein ab tere yeh sar jhukana hai - I will bow my head in your respect.
