Surah 10. Yunus

55Here the word (ummat) does not merely mean a nation or a community but includes all those people whom the Message of a Messenger reaches after his appointment, even though he be not alive among them. More than this: as long as his teachings remain intact and within the reach of everyone to ascertain what they really are, all such people will be treated and judged as his ummat and their cases decided with justice in accordance with v. 47. According to this standard, all the people of the world are the ummat of Prophet Muhammad (Allah's peace be upon him), and will remain so, as long as the Qur'an continues to be published in its original and complete form as today. That is why it has not been . said, "There is a Messenger in every ummat" but "There is a Messenger for every ummat. "

56That is, when the Message of a Messenger reaches a people, they should know that henceforth they are on trial and that no excuse would be accepted that they were ignorant of it. Then judgment is passed on them with scrupulous justice. Those, who accept the Message and mend their way in accordance with it, are declared to be worthy of Allah's blessings, and those who reject it are doomed to a torment that may be inflicted both in this world and in the next World or only in the Hereafter.
