What is the virtue of praying the Eid Al-Fitr prayer in the Grand Mosque after performing Umrah?

Performing Umrah in Ramadan holds immense virtue, as the Prophet, peace and blessings be upon him, said: "Umrah in Ramadan is equivalent to Hajj." Acts of obedience are multiplied in the Haram, for prayer in the Sacred Mosque is equivalent to one hundred thousand prayers. Eid prayer in the Sacred Mosque is more virtuous than performing it in an ordinary prayer ground, due to its فضيلة (virtue) and sharaf (honor), and the فقهاء (jurists) have explicitly stated this and reached a consensus on it.
