Despite their communication during the tutoring is without face-to-face contact (because as per the Muslim tradition, Husna remains in Parda or behind the veil), they recognize each other but some mistaken identities lead to Husna's friend, Naseem (Ameeta) falling in love with Anwar. Anwar who is the younger brother of a ordinary stage dancer, Najma (Nimmi) gets the job to tutor poetry to Husna who is the younger sister of an erstwhile Nawaab (king), Akhtar (Ashok Kumar). Fate and the efforts of Anwar's Hindu friend, Ghaayal (Johnny Walker), bring Anwar and Husna together. She at once comes to understand that the dashing youth singing on the mike is addressing to none else but herself only. He sings a song expressing his restlessness to see her - Mere Mehboob Tujhe Meri Mohabbat Ki Kasam, Phir Mujhe Nargisi Aankhon Ka Sahaara De De - in the auditorium of the college (in a poetry contest) and wins the heart of his lost sweetheart who is seeing and listening to him while sitting there as a part of the audience. Now Anwar is in search of his sweetheart whose fingers (or hand) only were seen by him and left their imprint on his heart. Mere Mehboob starts with the above-mentioned highly romantic encounter of Anwar (Rajendra Kumar) and Husna (Saadhana) in the college campus.
