Translation is defined as the process through which data and information are transferred between languages for scientific and cultural exchange. This study concerns introducing the significance of translation in a multi- cultural country and finding out the possible way to build up and promote coexistence in Sri Lanka via translation processes. The researcher used descriptive and analytical methods to complete this study. To meet the objectives of the study, the primary and secondary data were used with qualitative and quantitative approaches. The study concluded that translation is essential in multilingual and multicultural countries such as Sri Lanka. It can bring about co-existence and peace and build sustainable development. At a time, when Sri Lankan Muslims are facing various problems, translation will play the role of conveying Islamic teachings in Arabic into local languages and making understanding among the people of Sri Lanka.
