Is drinking the water of Zamzam one of the rituals of 'Umrah?

Question:
He says: Does drinking the water of Zamzam count as one of the rituals of 'Umrah? And if I do not do it, is there anything required of me?

Answer:
Drinking from the water of Zamzam is a recommended practice (sunnah) because it is blessed water and it follows the example of the Prophet (peace and blessings be upon him), for he drank from the water of Zamzam. So, if you have entered the state of ihram for 'Umrah or Hajj, and then you came and performed tawaf and sa'y—performed tawaf around the House seven times and prayed behind the Maqam before going to do sa'y—it is recommended that you drink from the water of Zamzam.
Unless you are fasting; it is not permissible for a fasting person to drink. But if you are not fasting, it is recommended that after the tawaf and sa'y for 'Umrah or Hajj—specifically the tawaf for 'Umrah or Hajj before you go to do sa'y—you drink from the water of Zamzam. This is a recommended practice (sunnah) and not obligatory. If you leave it, you owe nothing.
