Zakat is one of the five pillars of Islam and was made obligatory on Muslims in the 4th year after Hijrah (migration of Prophet Muhammad PBUH from Makkah to Madinah).

This important religious duty requires Muslims to give a fixed portion of their wealth to those eligible, mainly poor and needy Muslims.

The imposition of Zakat in 4 Hijri helped organize the community and ensure support for less fortunate members.

Understanding the year when Zakat was imposed gives insight into the early development of Islamic society and its social justice system.

This knowledge is essential for students of Islamic history and helps in understanding the timeline of Islamic teachings.
