The Bhakti movement and Sufi movement were both religious and spiritual movements that emerged in medieval India. They shared many common aspects, such as personal love for God, mysticism, and visiting holy shrines. However, the aspect that is not common to both movements is the worship of idols.

In the Bhakti movement, followers believed in the concept of one supreme God and focused on developing a personal relationship with Him through intense devotion and love. They did not believe in the worship of idols and emphasized the worship of God in a formless manner.

On the other hand, the Sufi movement emphasized the mystical aspect of Islam and aimed to achieve a direct spiritual connection with God. While Sufis did not worship idols, their practices often included the veneration of saints and holy shrines.

Therefore, option 2 - worship of idols, is the aspect that is not common to both the Bhakti movement and Sufi movement.
