Zakat is the obligatory giving of a portion of one’s wealth to those in need. It is considered a form of purification and an expression of solidarity with the less fortunate. Zakat is typically calculated as 2.5% of one’s savings and wealth above a certain threshold (nisab) and is distributed to categories specified in Islamic law, such as the poor, needy, debtors, and travelers.

Hajj is the pilgrimage to the holy city of Mecca in Saudi Arabia, which every adult Muslim who is physically and financially able is required to undertake at least once in their lifetime. It occurs annually during the Islamic month of Dhu al-Hijjah. The rituals of Hajj, which include circling the Kaaba, walking between the hills of Safa and Marwa, and standing in vigil on the plains of Arafat, commemorate the actions of the Prophet Ibrahim (Abraham) and his family and symbolize the unity of the Muslim ummah (community).
