The two Grand Mosques in Makkah and Madinah offer visitors the opportunity to drink from the water containers inside. This includes the famous Zamzam water, which holds great significance for pilgrims. It is recommended to drink Zamzam water in your accommodation and during your trip, and bottles are available for purchase at affordable prices in both cities. However, visitors should be cautious of buying from street vendors at inflated prices.
While Zamzam water is known for its purity, it is important to avoid exposing it to direct sunlight as this may cause interactions with plastic containers. Additionally, pilgrims should familiarize themselves with the regulations of their airline and customs regulations in their country to ensure compliance with allowed volume and required procedures for carrying Zamzam water on their flight.
