Islam  gives  freedom  to  people  to  choose  their  religions  in accordance with their will and faith as stated  in the Qur’an,2:256. For practitioners, the meaning of religious conversion is closely related to personal dimension that  they feel; conversion as the shifting from something bad into the good one, the shifting from one religion into another, the shifting from inappropriate side into the appropriate side, and the appropriateness  of long process of finding the God. For the religious elite, religious conversion is one dimension of religious freedom, which is closely related to  the  esoteric  dimension experienced and  perceived by  the practitioners. Besides, pragmatic-practical motive in the form of marriage and promotion cannot be avoided in conversion case. In wider context,  conversion can be understood  as one of positive influence of inter-religious relationship in plurality context. However, it can be also a negative influence when the conversion is not based on strong belief in the new religion. Otherwise, the conversion is based on contemporary interest of the practitioners which is pragmatic  and practical.  The phenomenon  of religious conversion mostly becomes destructive  potential for the building of religious harmony, as in the religious community have triumphalistic ideology.
