"This ummah of yours is a single ummah, and I am your Lord, so worship me. But they were cut off from one another in the matter of their unity, and yet they will all return to Us." [Sûrah al-Anbiyâ': 92-93]
The Arabic word "ummah" as it is used in these verses means: "people united by faith". This particular meaning for the word "ummah" is often see in the Qur'ân. For instance, Allah says: "Humanity was a single ummah and Allah sent Messengers with glad tidings and warnings..." [Sûrah al-Baqarah: 213]
"This ummah of yours is a single ummah, and I am your Lord, so worship me." [Sûrah al-Anbiyâ': 92]
This verse is preceded by a lengthy account where Allah relates to us the stories of various prophets like Moses, Abraham, Jesus, Zachariah, John, and others (peace be upon them all). Then Allah praises them, mentioning Mary, the mother of Jesus along with them, though she was not a Prophet, and concludes by saying: "This ummah of yours is a single ummah, and I am your Lord, so worship me."
