Zakat is the most powerful Islamic instrument to support impoverished people around the world. Zakat helps to reduce poverty by increasing the empowerment level of mustahiq economics. However, ways in which the Zakat supply chain can be promoted need to be investigated. The objective of this study, the first of its kind, is to examine the role of Zakat hashtags in promoting the Zakat supply chain and mustahiq economics. Additionally, this study examines the role of Zakat awareness and marketing politics. To achieve the objective of this study, primary data were collected from various employees of Zakat collection institutions in Indonesia. The data were analysed using partial least square structural equation modelling (PLS-SEM). The study found that Zakat hashtags play a major role in increasing Zakat awareness. It also plays an important role in increasing marketing politics. Zakat awareness and marketing politics increase the Zakat supply chain, a mechanism that ultimately increases the empowerment level of mustahiq economics.
